The formula for Sierpinski conjectures in CRUS is k*b^n+1
The formula for Riesel conjectures in CRUS is k*b^n1 The formula for Sierpinski conjectures in this project is (k*b^n+1)/gcd(k+1,b1) The formula for Riesel conjectures in this project is (k*b^n1)/gcd(k1,b1) Last fiddled with by sweety439 on 20201011 at 16:38

All n must be >= 1.
kvalues which make a full covering set with all or partial algebraic factors are excluded from the conjectures. kvalues that are a multiple of base (b) and where (k+1)/gcd(k+1,b1) (+ for Sierpinski,  for Riesel) is not prime are included in the conjectures but excluded from testing. Such kvalues will have the same prime as k / b. Last fiddled with by sweety439 on 20201011 at 16:40

S876 and R876 have 59029 S966 has 71707 Like the status for both sides for base 728, which has 105997 Last fiddled with by sweety439 on 20201013 at 07:22

Now, the CK for all Sierpinski/Riesel bases <= 1024 except SR156, SR280, SR876, SR910, R946, SR960, SR966 (which have too large upper bounds) are known!!!

See https://github.com/xayahrainie4793/E...0to%202048.txt (Sierpinski) and https://github.com/xayahrainie4793/E...0to%202048.txt (Riesel) for the CK's for bases 2 <= b <= 2500 and b = 4096, 8192, 16384, 32768, 65536

No other (probable) primes found for R70 k = 376, 496, 811 up to n=22813

Also all kvalues such that numerator(k*b^n+1) (+ for Sierpinski,  for Riesel) divides (b1)*b^r for some (positive or negative or 0) integer n and (positive or 0) integer r
