I think it is more the following situatiuon: 95+% done, connecting to prime.net - GET NEW WORK !! - start with new work ! After 5-7% the old workfile gets it's active flag back and will be completed. This situation is really b*llsh*t, imagine the new number is very high, it tooks 1

Mersenne: M(2) - composite?!

2001-07-31 Thread Nathan Russell
Hi all, I'm a bit puzzled. The other day, I donated blood and kept my mind busy by doing LL tests on a few exponents mentally. I kept getting the result that the LL test for M(2) ends up resulting in a repeating value of -1, and certainly cannot ever become zero. Am I missing something really

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:

Mersenne: Managing factor lists

2001-07-31 Thread Andrew John Walker
I'm after a simple program that can manage a list of factors. With some expression dependant on a single variable such as n, I'd like it to be able to accept new factors for a given n, check they are factors, then rewrite the factor list including the length of the remaining cofactor. I'd be

Mersenne: Suggestion for mprime documentation

2001-07-31 Thread Gerry Snyder
I would have just sent this to George, but I thought others might want to comment. I think the -m (menu) option of mprime deserves better press. The only negative about starting mprime with it it is that the menu choice of 6 is needed to start LL checking (or whatever). After that the -d
