nice one uncwilly

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).

P-1 found a factor in stage #2, B1=550000, B2=10312500.

(M1061)+1 has factor: 2

[COLOR=White]Sorry, boredom got a hold of me :/[/COLOR]

has it any other prime factor?

[QUOTE=firejuggler;319431]has it any other prime factor?[/QUOTE]
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

I've done a little bit of work on the low 400s, since the entire range seems to be neglected...

Yeah, P-1 of course :smile:
...Found quite a while ago though, heh by my laptop.
