Keyword：congruence number，Elliptic Curves，Number Theory,Group 0 History background Since the 10th century AD, the Persian mathematician AlKaraji has raised the problem of congruence, and it has been more than a thousand years [1] 1855,Genocchi proved the primes p≡3(mod 8) are all not congruence [2]； 1874,Genocchi proved if primes p≡5(mod 8),then 2p are all not congruence [2]； 1915,Bastien proved if primes p≡9(mod16),then 2p are all not congruence [2]。 1952,Heegner & Birch, if primes p≡3(mod4). then 2p are all congruence [2] 1975,Stephens the primes p≡5,7(mod 8) are all congruence [2] Alter,Kurtz & Kubota came up with conjecture: primes p≡5,6,7(mod 8) are all congruence(Not certified yet) [2] Identify the following issues with congruence: 1．Seeking a discriminant rule to determine whether a n∈N is a congruence (not completely resolved yet) 2．If the n∈N is a congruence , how to find the corresponding right triangle. (Not resolved at all) 3．Structure of the solution of congruence no one has ever studied, this paper finds and proves that the number of types of congruence solutions is the power of 2.new conjecture is proposed for the types of congruence solutions. The author of this paper constructs a new function for the first time, which is called the upper bound estimation function. 1. When the value of this function is 1, the corresponding positive integer A must be a noncongruence number. (Developed the author's N1 criteria) 2. When the positive integer A is a congruence, the value of this function corresponding to A is 2^k,where k≥1 3. When the solution of congruence A is not easy to find,using the intermediate result of this function can provide the search direction, For example, A = 822, we have not find the corresponding (s, t) solution, but this function provides 822. there is a solution of type (1,1, 2,411), which is helpful for the solution. 1 Existing judgment theorem or conjecture: 1.1 Fermat, Keqin Feng, Ye Tian and other existence theorems. Theorem A) Fermat's discriminant theorem: A is the congruence ,if and only if the system of equations: x^2+Ay^2=z^2 x^2Ay^2=w^2 There is a positive integer solution with y≠0 Theorem B). Existence theorem (Keqin Feng 1996, Delang LiYe Tian 2000, Chunlai Zhao2001) We have an infinite number of noncongruences with an arbitrary number of odd prime factors. In addition, there are an infinite number of congruences of a specified number of odd prime factors. [3] Theorem C). (2009, Xungui Guan) The necessary and sufficient condition for n to be the congruence is: there are positive integers a, b,v such that: nv^2=6a^2 b^2a^4b^4 or 4ab(a^2b^2) (Note: There are only two forms [4] 1.2 Practicality theorem: Theorem 1) Positive integer n=2p,where p≡3 (mod 4), n is the congruence .(Heegner,Birch) Theorem 2) Positive integer p≡5,7 (mod 8), p is the congruence .(Stephens[2],p276) Theorem 3) Set p_0≡5,7(mod 8) (Respectively p_0≡3(mod 4) ), p_i≡1(mod 8), i=1 …k, p_0,p_i Is odd prime and satisfies: (p_i 〖/p〗_0)=1), i=1, … ,k, and (p_i 〖/p〗_j)=1, 1≤ j ≤i1 then: n=p_0 p_1…p_k (Respectively n=2p_0 p_1…p_k） is the congruence (Ye Tian,2012)[5] Theorem 4) Let the expansion coefficient of the BSD modular function be a_n, b_n ,where n Is a square free positive integer, when a_n≠0, then n is not congruence, when b_n≠0, Then 2n is not a congruence r..[Coteswiles,1979] Theorem 5) Prime number p≡3 (mod 8), then p is not a congruence . (1855,Genocchi Theorem 6). Positive integer p≡5 (mod 8), then 2p is not a congruence.(1874,Genocchi) Theorem 7) Prime number p≡9 (mod 16),then 2p i s not a congruence .(1915,Bastieni) Theorem8)Integer n=pq,here p,q≡3 (mod 8), n Is’t a congruence (2019, ConyaoZhou,Wei Yu,XiaoningTang)[6] Theorem 9)Integer n=pq here p,q≡3(mod 8),2pq Is’t a congruence (2019,ConyaoZhou,Wei Yu,XiaoningTang) [7] Theorem10) Prime number p,q≡5 (mod 8),then 2pq is’t congruence (2019 ConyaoZhou,Wei Yu,XiaoningTang) [7] Theorem11) For the Integer A, as long as it has no solution at the N1 positions of the factor combination, then A is not a congruence (2019 ConyaoZhou,Wei Yu,XiaoningTang) [8] For more than 1,000 years, only these 11 theorems have practical value,Three of the judgments were yes and eight were negative. 1.3 Three conjectures: BSD Conjectural modular function: Let g_n=T∏_(n=1)^∞▒〖(1T^8n )(1T^16n ), 〗 θ_k=1+2∑_(n=1)^∞▒T^(2kn^2 ) k=1,2 g_n θ_1=∑_(n=1)^∞▒〖a_n T〗^n , g_n θ_2=∑_(n=1)^∞▒〖b_n T〗^n 1)BSD conjecture:Let n be a positive integer without a square factor, when a_n≠0,then n is not congruence, b_n≠0,then 2n is not congruence, when a_n=0, then n is congruence, b_n=0, then 2n is congruence, 2）AKK conjecture:(Alter，Kurtz & Kubota):p≡5,6,7(mod 8) is all congruence, 3）Tunnell conjecture:(Actually, it is an equivalent conjecture, but its calculation of 〖 a 〗_n,b_n is much easier than BSD ) Assuming that the BSD conjecture is true, If n is an odd square free number, define: f_1={(x,y,z)∈Z2x^2+y^2+8z^2=n}, f_2=2{(x,y,z)∈Z2x^2+y^2+32z^2=n }, a_n=f_1〖2f〗_2 If n is an even square free number, define: f_1={(x,y,z)∈Z4x^2+y^2+8z^2=n/2},f_2=2{(x,y,z)∈4x^2+y^2+32z^2=n/2 } a_n=f_1〖2f〗_2 Then n is Is the congruence quivalent to a_n=0 (Not proven yet). Since the case of analytical rank 0 has been proved, therefore a_n≠0 can be launched n is’n congruence. Using this method, you can effectively verify a noncongruence number. The problem is that when n is relatively large, the calculation f_1，f_2 very slow , In particular, calculating the coefficients a_n,b_n not only is it slow, but the value of the intermediate process is huge, Despite this, the BSD conjecture is still the most wonderful at present, but unfortunately it cannot be proved. 2. Preliminary theorem Preliminary theorem 1: Let f(x)=a_n x^n+a_(n1) x^(n1)+…+a_0 Is an algebraic equation with integral coefficients, m=p_1 p_2…p_k, T(f,m) express the number of solutions of f(x)≡0 (mod m) ,where p_i is prime. Then this congruence equation and congruence equations:f(x) ≡0 (mod p_i) i=1,…k, is equivalent, and T(f,m)=T(f, p_1) T(f, p_2)…T(f, p_k) [9] Theorem 1 of p182 That is to say, as long as one equation in the congruent equation system has no solution, the congruent equation system has no solution as a whole. 2.2 Preliminary theorem 2: Set ax^2+by^2+cz^2=0, where abc has no square factor, a、b、c not all are positive or negative, If and only if S^2≡ab (mod c), S^2≡bc (mod a and S^2≡ca (mod b) when all have a solution, quadratic equation ax^2+by^2+cz^2=0 only have integer solutions.[9] Theorem 1 of p282.. Preliminary theorem 3:(Congyao Zhou,Wei Yu,Xiaoning Tang,2019): If A is a congruence number, there are at least two types of solutions (s,t),(S,T), The latter is of type Fermat. Where S=〖(s^2+t^2)〗^2, T=4Am^2=4st(s^2t^2) 【Prove】Any positive integer s,t,(s,t)=1 s>t, and s,t An odd and an even s,t is not of type: 〖(a^2+b^2)〗^2 and 4ab(a^2b^2) Assume (s,t) is Is a solution of congruence A, by definition then Am^2=st(s^2t^2). Let S=〖(s^2+t^2)〗^2, T=4Am^2=4st(s^2t^2), For (S,T): S is a perfect square,T=A〖(2m)〗^2 then T = A multiply with a perfect square S+T=〖(s^2+t^2)〗^2,+ 4st(s^2t^2)=(s^2t^2+2st)^2, is a perfect square. ST=〖(s^2+t^2)〗^24st(s^2t^2)=(s^2t^22st)^2, is a perfect square. so another solution (S,T) corresponding is also the congruence A, and (ST,T,S,S+T)=(1,A,1,1）, Which is of type Fermat, Conversely, if a positive integer s,t, (s,t)=1 s>t s,t An odd number and an even number s,t is the type of 〖(a^2+b^2)〗^2 and 4ab(a^2b^2) can be obtained s_0=a,〖 t〗_0=b, s_0,t_(0 ) and s,t are all correspond to congruence A, (s_0,t_(0 ))≠(s,t), That is also at least 2 types of solutions. Theorem is proved. note: In fact, always get a small set of solutions first (s,t), Then use the formula to get the second type of solution (S, T) For example, the solutions of the 6 smallest two types are (2,1) and (25,24), the types are (1,1,2,3), (1,6,1,1) the solutions of the smallest two types of 1254 are (11,8) and (34225,20064), the types are (3,2,11,19), (1,1254,1,1) 3. Symbols and definitions Definition 1: Type of solution Let the explicit solution of primitive congruence A be: A×m^2=(st)ts(s+t),there m=xyzw, Here x,y,z,w is respectively maximum square factor of (st),t,s,(s + t),thisis x^2(st), y^2t, z^2s, w^2 (s+t) Let a=(st)/ x^2 ，b=t/y^2, c=s/z^2, d=(s+t)/w^2 ,then A=abcd is primitive congruence. st(s+t)(st) is the area of a right triangle, m^2 Is the square factor in the area of the right triangle. We call s, t the solution of the congruence A; The quaternion (a, b, c, d) is the type of solution; At the same time, we call (a, b, c, d) = (1, A, 1, 1) a Fermat type solution. Algorithm from solution to type (s,t)→(st,t,s,s+t) respective, remove the maximum square factor, get (a,b,c,d), On the contrary, there is no effective way. E.g : Minimum solution of 5 is (s,t)=(5,4), (s,t) → (st,t,s,s+t)=(1,4,5,9), → (a,b,c,d)=(1,1,5,1). Minimum solution of 1254 is (s,t)=(19,8), →(st,t,s,s+t)=(11,8,19,27), → (a,b,c,d)=(11,2,19,3). When it does not cause confusion, sometimes a symbol, such as english letters or numbers or greek letters, is used as a short name for the type. Definition 2: Number of factor combinations N=Y(A), Here A is a positive integer without a square factor, and the element of the factor combination is denoted as C1, C2, ..., Cn, ... ,the lowercase symbol ci = its value ( 1 or 0 ) The number of factor combinations of A is as: Y (1) =1, Y(p)=4 where p is an odd prime number. For composite number A, multiply each odd prime factor by 4, if it contains 2, then multiply by 2. ∵ 6=2*3, ∴Y(6)=8； ∵ 15=3*5, ∴ Y(15)=16； ∵1254=2*3*11*19, ∴Y(1254)=128 ∵992221230= 2*3*5*7*11*13*19*37*47, ∴ Y(992221230)=131072 The algorithm from A to Ci is as follows: Factor A and arrange the prime factors from small to large; let the number of factors be r, Here Two intermediate arrays A1, A2 are used, and the final result is stored in the array Ci. If A is even, the initial state of A1 is two elements (1,2,1,1),(1,1,2,1); Otherwise A1 is four elements (p_1,1,1,1), (〖1,p〗_1,1,1), (1,1,p_1,1), (1,1,1,p_1); Let the number of elements in A1 be s 3) A1→A2. If factor number of A r=1, then goto 5) 4) if factor number of A r>1,, then for k=2 to r do: Change each element in array A1 from 1 to 4, write to array A2: Clear A2, A1(i,j)* p_k Order write into array A2(* , j). there i=1 to s, j=1 to 4 5)) Array A2 write to array Ci E.g 1: A=5 then A1=A2={(5111),(1511)(1151)(1115)}={C1,C2,C3.C4} E.g 2: A=6 then A1={(1211),(1121)}, A2={(3211),(1611)(1231)(1213), (3121),(1321),(1161),(1123)}={C1..C8} E.g 3: A=15 then A1={(3111),(1311),(1131),(1113)}, A2= {(15,1,1,1),(3,5,1,1),(3,1,5,1)(3,1,1,5), (5,3,1,1),(1,15,1,1),(1,3,5,1),(1,3,1,5) (5,1,3,1),(1,5,3,1),(1,1,15,1),(1,1,3,5), (5,1,1,3),(1,5,1,3),(1,1,5,3),(1,1,1,15)}={C1..C16} The correspondence between the factor combination Ci and A is fixed, We have an algorithm to automatically generate a complete set of factor combinations (see Appendix 10.1) Definition 3: Four equations Let a solution of primitive congruence A be A×M^2=(st)ts(s+t) Where:(s,t)=1; s>t, s,t is integer, an odd and an even , st,s+t must be odd, and st,t,s,s+t are mutually prime. For st,t,s,s+t see its parity, There are only two combinations: case A: odd odd even odd; case B: odd even odd.odd The corresponding right triangle side length is 2st, s^2t^2,s^2+t^2, area=(st)ts(s+t), The basic primitive congruence number A, the area of the right triangle, and the basic relationship of the right side are: :Am^2=st(s^2t^2 ), we call (s,t) an explicit solution of congruence, For the congruence number A, if (s, t) is obtained, then the solution is successful. There are four factors for the area of the triangle: st, ②t, ③s, ④s+t Corresponding to: ax^2, by^2,cz^2, dw^2 By defined ①②③④, Obtain the following four equations: (For any combination of factors (a, b, c, d) of A, if there is a solution, it is said (a, b, c, d) is the type of solution), the four equations are named Q1Q4: ax^2+by^2=cz^2 (Q1） by^2+cz^2=dw^2 (Q2) ax^2+dw^2=2*cz^2 (Q3） dw^2ax^2=2*by^2 (Q4) Definition 4: 12 discriminant equations There are three ways to use each equation, mod a or mod b or mod c,Corresponds to the second subscript j=1,2,3; There are 12 kinds of judgment methods. For example: from Q1) ax^2+by^2= cz^2 get S^2≡bc (mod a),notes q11, Available in total q11,q12,q13; q21,q22,q23; q31,q32,q33; q41,q42,q43. referred to as qij (i=1,2,3,4;j=1,2,3) As long as one of the 12 formulas is not true, this factor combination abcd has no solution, at this time, define qij=0 The converse is not possible. even if all the 12 formulas are true, it does not mean that this combination must be solvable, it is just suspicious. now define qij = 1 Definition 5: M8 set (Type of solution Modulo 8) For (s,t)=1,s>t,s,t an odd number and an even number, for (st,t,s,s+t)：caseA :ooeo case B: oeoo, where st=ax^2, t= by^2, s=cz^2, s+t=dw^2 And odd^2≡1(mod 8) E.g a=27, a’=3, x=3, 3^2≡1(mod 8) Also t=18, b’=2,y=3, y^2≡1(mod 8); t=12,b’=3,y=2, y^2≡4(mod 8); t=48, b’=3,y=4 y^2≡0(mod 8) In short b is even y^2≡{0,1,4}(mod 8) .

For the suspicious set, define M8 = 1 for this combination. There are 96 items in the suspicious set. (The red combination in the above table, define M8 = 1 at this time) Similarly, it can be proved that other 95 combinations are suspicious sets Here define its value m8=1; Let the factor combination be (a,b,c,d),some of them are definitely unsolvable, such as 1113; some are suspicious, that is, the solution of this combination cannot be determined, such as 1111 E.g: p=41, a’b’c’d’=1111, ∵41is congruence, ∴ The ternary quadratic system of course has solutions; Also p=17,a’b’c’d’=1111,∵17 is’t congruence, ∴The congruent equation system must be unsolved. Thus, M8=1111 cannot be determined by the M8 method, but it is only suspicious. Definition 6: The function of the upper bound estimate of the type of solution, abbreviation Z(A) The factor combination Y (A) has been defined. A as a positive integer without a square factor. We have an algorithm 1, which automatically generates all factor combinations. When searching to find the number of types of congruence number = Z (A),the type number is exact; define the value as T(A) = type number of congruence solution Definition 7: New function Let A is a positive integer without a square factor, If the qij and M8 of this combination are all 1, then this combination contributes ci=1, this is Z(A)=∑ci (lowercase c) E.g: A=17,Y(17)=4, C1= (abcd)=(17.1.1.1) Q1; 〖17x〗^2+y^2 〖z〗^2=0, S^2≡1(mod 17),q11=1; S^2≡17(mod 1) q12=1; S^2≡17(mod 1) q13=1 ∴Q1 has sulotion Q2; y^2+z^2 〖w〗^2=0 S^2≡1(mod 1), 21=1; S^2≡1(mod 1),q22=1; S^2≡1(mod 1) , q23=1 ∴Q2 has sulotion Q3; 〖17x〗^2+w^2 〖2z〗^2=0 S^2≡2(mod 17)q31=1; S^2≡34(mod 1),q32=1; S^2≡17(mod 2),q33=1 ∴Q3 has sulotion Q4; w^217x^2 〖2y〗^2=0 S^2≡34(mod 1)q41=1; S^2≡2(mod 17)q42=1; S^2≡17(mod 2)a43=1 ∴Q4 has sulotion M8=(abcd)(mod 8)=(1111) belong suspicious set of M8; qij, M8 of this combination be all 1, C1 contributes 1 to Z (A), C2,C3,C4 C1 contributes 1 to Z (A), so Z(41)=4 Definition 8．N1 guidelines If the value of the new function Z(A)=1, Then A is a noncongruence number, where N Is the number of factor combinations (see definition 2), [Prove] By Preparation Theorem 3,if A is congruence, Then there are at least two different types of solutions that is, at the N positions of factor combinations, at least, there are two places that appear to be solvable, In other words, at most at the N2 factor combination, the corresponding congruence equation may be found to have no solution And we have determined that the corresponding congruence equation has no solution at the N1 combination of factors, so A can only be noncongruence. If the value of the new function Z(A)>1, there is no clear conclusion. Example, Z(17)=4, And 17 is not a congruence number;Z(41)=4, but 41 is the congruence. Definition 9 . The exact value of the number of types of congruence solutions T (A) When the sequential search method and I⊕J method, or other methods, The number of types of solutions found is equal to the upper bound estimate Y(A), Define this value to be T(A), E.g T(6)=2, That is, there are only two types of solutions of the 6: (1123) and (1611). 4.

solutions of the same kind must be of type F, α+α=F (main diagonal) 2) Any type plus F, the type remains unchanged. (Row 25 or column 25) 3) Any row or column is an arrangement of 32 types, but it is not a permutation group. 4) F is equivalent to the 0 element of the group 5) Anything of the same type is inverse to each other 6) Satisfying the combination law (a⊕b)⊕c=a⊕(b⊕c); Satisfy the exchange law a⊕b= b⊕a 06: The most special ones are: If the three points of the elliptic curve P⊕Q=R, then Q⊕R≠P R⊕P≠Q,but the types of solutions corresponding to these three points αβγ, but if α⊕β=γ,then β⊕γ=α γ⊕α=β,we call this ternary cycle, This is a deeper relationship than the point group relationship we found. Here α and so on represent one of the solution types 19, ao, U, V, W, X, Y, Z, T, The above 32 groups have more than 180 ternary cycles, such as:123,145,16b,17e,189,1ak, 1cX, 1dL, 1fm, 1go, 1hi, 1jn, 1F1, 1UW, 1VT, 1YZ…： It can be seen from the matrix 1+U=W, We can use the ternary cycle to verify the relationship of any ternary cycle of this matrix : 1+U=(2+3)+(2+d)=3+2+2+d=3+(2+2)+d=3+F+d=3+d=W, ∴1UWForming a ternary cycle. Fill in the type at ①②③ 1,U,W, Rotate counterclockwise, there is ①⊕②=③,②⊕③=①, ③⊕①=②; Or rotate clockwise, there is ①⊕③=②,③⊕②=①,①⊕③=② Fill in type a, a, F, rotate counterclockwise a⊕a=F,a⊕F=a,F⊕a=a 07: Closed and complete (For some examples are insufficient due to sequential search. although a closed set is formed, it is not a complete set) The above matrix is fully affirmed 253375990 its type of solution is a group of order 32. Note ：Due to the limitation of calculation time or space, the sequential search method and the elliptic curve group addition algorithm ⊕, for most congruences, can only reach incomplete partial solution types, Misjudgment may occur， Take this example, if it is restricted by time and space, the following will happen: 1):If only the first solution is found J1：s=611, t= 10 its type(abcd)=(601.10.611.69), With elliptic curve group addition, only one new type F=(1A11) can be added, The solution is s=139443243241,t=9121521240 The solution process is abbreviated as 01 + F, although Z (A) = 32, it is also useless, and can only be misinterpreted as a 2order group. 2):If only the first two solutions are founds J1,J2, look at the two rows and two columns of the above matrix： J1⊕J1=F,J2⊕j2=F,J1⊕J2=J3Misjudged as 4th order group, the solution process is abbreviated as 02+F+01 3): If only the first 3 solutions are found J1,J2,J3, Look at the first three rows and columns of the above matrix: J1⊕J1=F,J2⊕j2=F,J3⊕j3=F, J1⊕J2=J3,J1⊕J3=J2, J3⊕J1=J2, Would be misjudged as a 4order group,03+F 4): If only the first 4 solutions are found J1,J2,J3,J4, Look at the first 4 rows and 4 columns of the above matrix: J1⊕J1=F,J2⊕j2=F,J3⊕j3=F,J1⊕J2=J3,J3⊕J1=J2, J2⊕J3=J1…, The situation has improved, the solution process is abbreviated as 04+F+03， It means that the sequential search found 4 types 1, 2, 3, 4 and ⊕ operation found F, 5, 6, and b. Since the I⊕J operation can no longer add new classes, it can only be misjudged as an 8order group. 5): If only the first 5 solutions are found J1,J2,J3,J4,J5 Look at the first 5 columns of the 5 rows of the above matrix J_i⊕J_i=F,J1⊕J2=J3,J1⊕J3=J2, J3⊕J1=J2… The situation has not improved, the solution process is abbreviated as 05+F+02, It means that the search found 5 types 15, ⊕ operation found F, 6, b, but it can only be misjudged as an 8order group 6) If only the first 6 solutions are found J1J6 Look at the first 6 columns of the 6 rows of the matrix, The solution process is abbreviated as 06 + F + 01, and the type is misjudged as an 8 order group 7): If only the first 7 solutions are found J1J7 Look at the first 7 columns of the 7 rows of the matrix, The solution process is abbreviated as 07+F+07;+01, type misjudged as 16. 8): If only the first 8 solutions are found J1J8, Look at the first 8 columns of the 8 rows of the matrix,, The solution process is abbreviated as 08+F+09;+14, type misjudged as 32. 9): If only the first 8 or more solutions are found, they can all be correctly identified as order 32, but the discovery process x + F + y; z is different 08: This 32order group has more than 160 4order subgroups, and more 8order subgroups. (For example, delete c from the abcF of the ternary cycle and add one of the 28 types, which is the 8order group) We have discovered and proved that the number of types of solutions for 5 different congruence numbers is the 32order group, announced as follows: A Y(A) z(A) T(A Solution process 253375590 8192 32 32 09+F+15;+07 277872990 8192 32 32 13+F+17;+01 565004406 2048 32 32 06+F=12;+13 840075621 16384 32 32 14+F+16;+01 904789886 8192 32 32 06+F=12;+13 Theorem 7.8) Any type of solution α satisfies the relationship α⊕α=F [Prove] Observe the relationship on the main diagonal of the matrix：α⊕α=F Let a solution of A be s,t,then Am^2=st(st)(s+t), Corresponds to a point on an elliptic curve P=(x,y) Its coordinates x=((s^2+t^2)/2m)^2 y=(s^2+t^2 )(s^2t^2+2st)(s^2t^22st)/(8m^3 ) (8.1) Use the tangent method of the elliptic curve: Slope L_2=(3x^2A^2)/2y = (3((s^2+t^2)/2m)^4A^2)/(2 (s^2+t^2 )(s^2t^2+2st)(s^2t^22st)/(8m^3 )) = (3〖〖(s〗^2+t^2)〗^4〖16A〗^2 m^4)/(4m(s^2+t^2 )((s^2+t^2 ) )  〖〖(s〗^2t^2)〗^24s^2 t^2 ) Let 2P = (X, Y) solution correspond to S, T according to the author's own lemma AM^2=ST(ST)(ST) S=〖〖(s〗^2+t^2)〗^2 T=4Am^2 L_2=(3〖〖(s〗^2+t^2)〗^4〖16A〗^2)/2M where M=2m(s^2+t^2 )((s^2+t^2 ) )  〖〖(s〗^2t^2)〗^24s^2 t^2  X=L_2^22x=〖((3〖〖(s〗^2+t^2)〗^4〖16A〗^2 m^4)/2M)〗^2(2〖〖(s〗^2+t^2)〗^2)/(4m^2 ) = 〖〖(3S〗^2T^2)〗^2/(4M^2 )  2S/(4m^2 ) =〖(3S^2〖16A〗^2 m^4)〗^2/〖(2M)〗^2 (2SM^2/m^2)/(4M^2 )=(9S^46S^2 T^28S^4+8S^2 T^2)/(4M^2 )=〖〖(S〗^2+T^2)〗^2/(4M^2 ) , The X of the 2P point is the same as the x structure,and it is substituted into the curve equation Y^2= X(X^2A^2) get Y. Replace the lowercase s,t,m in the y formula of (8.1) with uppercase, In this way, the structure of X and Y is exactly the same as that of x and y in (8.1). For ST,T,S,S+T Its structure is 1A11, That is, Fermattype solution, proved complete. Note:∵AM^2=ST(S^2T^2)=S(4Am^2)( S^2T^2) Both sides Multiply on both sides 2S/(Am^2) get 2SM^2/m^2=8 S^2( S^2T^2) substitute into the above formula theorem 7.9:Types of congruence solutions=2,4,8,16,32, Proof of the calculation of millions of congruences [Prove] Introduced tys_200w_tj in Appendix 10.4 The calculation and significance of the three fields bz, IJ and up in the table , here is a table to illustrate our proof.

New function, new criterion, new theorem and new conjecture for discriminant of congruence number
New function, new criterion, new theorem and new conjecture for discriminant of congruence
Zhou CongYao College of Information Science and Engineering, Hunan University Yu Wei Department of statistics & financial engineering,College of mathematics and statistics,ningbo university TangXiaoNing Beijing Haitian Start Technology Service Co., Ltd. ABstruct In this paper,a new function of congruence discrimination is proposed,namely,the upper bound estimation funtion of the number of solutions of the congruence. If the value of this function is 1,the posttive integer A is noncongruent,this is the new N1 criterion.Using this guideline, to history all 3 congruence negative theorms,a very simple elementary proof is given;and proved the author's newly discovered three modular 8type congruence negative theorems; At the same time,eight new congruences negation theorems(not model 8 types) are proved,by the way,we derive 1511 infinite sequences of noncongruent If A is a congruence number,the value of this function is integer power of 2,that is,there are at least two types of solutions for congruence,one of them must be Fermat type,and each type has an infinite number of solutions. Using this upper bound function, some new theorems for the number of congruence solutions are derived: the exact value of the solution is 2, 4, 8, 16, 32; On this basis, a new conjecture is put forward: If the type of the congruence solution is used as an element, then these elements form a group,and the order of this group is integer power of 2 ,for any congruence, the conversion relationship between the types is fixed.

"the congruence". One must ask: What congruence?? Does he refer to what is known as "the congruent number problem"?
