nice find! I hope that anonymous guy read the forum from time to time! Or at least I hope he did not start it, so P95 will detect the invalid key and cancel it, saving the guys a lot of time, computing power and energy (P95 does not cancel an assignment if work was already done on it).

(M1061)+1 has factor: 2

Sorry, boredom got a hold of me :/

firejuggler · 2012-11-23, 17:47

has it any other prime factor?

Yes. There are 1060 more factors of 2 that can be taken :)
If you mean other than 2, I'm afraid that's a negative. :P

The biggest factor I have is
18164039969328095522036298121273856953
Exponent=53324207
Bit Level=123.77

Yeah, P-1 of course

...Found quite a while ago though, heh by my laptop.
