Early versions of Prime95 had P-1 bugs so there's lots of P-1 efforts from circa 2000-2005 that missed lots of factors.

But aside from that, there are still a (small) number of P-1 failures still...

Tried it again on my other computer. At least with current versions of Prime95 it does report factors separately (presumably it was the same in 2006 but I didn't bother to dig out such an old...

On the basis of how many tests I tell Prime95 will be saved in the worktodo line. Same as always. Obviously no Mersenne primes will be discovered, nor candidates eliminated, when running P-1 on an...
