Christenson,

Hmm, very interesting, thanks! I want to look some more into this. Maybe we should take this thread over to Hardware/GPU Computing before the Forum Gods suggest that we're off-topic...

I'm gonna celebrate the first one I find!!!!

M3321936361 factored from 60.000 bits to 71.000 bits,
and it has a factor: 924868354347418664233.

These four have been taken to 82 bits with no factor:

3321933577
3321933613
3321933661
3321933679

However, I'm gonna take them an extra level to 83 bits.

Edit: I hope no-one takes any more candidates to 82 bits. When firejuggler finishes his current batch, it'll be just two more to 82 bits to finish the level, and I have a strange neurosis that makes me want to see two levels rounded out at the same time (including taking the last couple of candidates from 82 to 83 bits before doing 81 to 82 bits (simultaneously of course) :geek:).

I'm just throwing this out there, I hope everyone else has this same weird desire, or at least doesn't mind indulging me.

Lavalamp, I'm OK with you going simultaneously to 82 and 83 bits as long as there is stuff below 81 bits for me to keep raising the floor on...which will take me at least a month.
