LucasLehmer test proof etc.
First if possible I'd like a link to PARI ( suggested last time I posted on here) I've reformatted since then I don't see how to install it! I was looking about the proof of the Lucas Lehmer test and I know it proves that the s values that show primality are all multiples of the prime they prove ( or I think it was that). This got me thinking to figure out what multiplies by the primes to get these results and I came across 607 another prime Mersenne exponent. I was going to suggest it might be a way to find higher Mersenne exponents ( not a good idea on here) but can anyone help verify at least that all the other results of the divisions are prime ? maybe then I'll see if I can find a proof of Mersenne Prime exponents in them all.

the results like 14/(7*2) and s(3)/(31*2) where s is it's value in the lehmer test. I'm multiplying by 2 on bottom as I find that the results I see so far divide by 2 at least

Ok..
Not sure where you are going.. but
MP2  4/ (3 * 2) = 0 MP3  14/ (7 * 2) = 1 S(2) = 14 MP5  62/ (31 * 2) = 1 S(2) = 14 S(3) = 194 S(4) = 62 MP7  12319/ (127 * 2) = 48 S(2) = 14 S(3) = 194 S(4) = 4487 S(5) = 1762 S(6) = 12319 MP11  79522/ (2047 * 2) = 19 S(2) = 14 S(3) = 194 S(4) = 37634 S(5) = 620942 S(6) = 491399 S(7) = 14159 S(8) = 3523127 S(9) = 57598 S(10) = 79522 You do realize that that last s should be MOD MP and = 0 when MP is prime... but the rest of prime P < 64 see... http://dotnetmath.alexanderhiggins.c...jecture_a.aspx

not exactly where I wanted to go I was going more for:
http://www.research.att.com/~njas/sequences/A003010 when divided by the proper id:A000668 seems when divided by 2 to give a prime(asking for verification of that) (in fact one I tried gave 607(a mersenne prime exponent)) Last fiddled with by science_man_88 on 20100304 at 23:39

Now why would I want that? As long as it's kept to the Misc Math forum, I'm fine with it. Sometimes I even find these threads amusing (in a way). Last fiddled with by TimSorbet on 20100304 at 23:51

14/7 = 2 2/2=1
37634/31=1214 1214/2 = 607 < prime exponent 2005956546822746114/127 = 15794933439549182 that / 2 = 7897466719774591< possible prime exponent ? basically I'm trying to find a way to use http://www.research.att.com/~njas/sequences/A003010 to find something useful ( such as exponents that work)
