ss of credit.  Is this up-to-date stat policy?  Does this apply only to LL stats or is it possible to lose credit for factoring if later factoring proves more successful?  How many such scenarios are there?   Thanks, Carleton Garrison

How did you get -1? Lucas-Lehmer Test: For p odd, the Mersenne number 2p-1 is prime if and only if 2p-1 divides S(p-1) where S(n+1) = S(n)2-2, and S(1) = 4. You missed the premise "for p odd". And even so, S(p-1)/(2p-1) with p = 2; S(1)/3 = 4/3. Carleton - Original Message - From: "N
