Man, that is some big iron there.....hope I can manage that one day!

At iteration 2680; C141. I've done a bit of ECM on it - no point anyone else running curves below B1=3e7. I don't intend to do GNFS on this one.

I see we've already dodged our first 2*p bullet (line 2674)...

The c141 will make a good test case for yafu's new and improved gnfs capabilities. I can start it this evening if ecm hasn't cracked it by then.

[strike]I guess this one will require a full t45 (~4480@11e6). @Fivemack: have you done any curves at the 11e6 level?[/strike]

Edit: I just see that I have misread fivemacks post, he seems to have done "full" 3e7 (which I've misread as 3e6 at the first time). So the c141 should be ready for GNFS.

If you want a jump start on the sieving, I ran poly search for a few hours and produced this one:

I'm probably being unclear; I did 960 curves at 3e7, which I think is not quite a full 11e6. I'd suggest to start sieving now; I've left a 3e7 ECM running overnight on a 16-thread machine but will stop it if that hasn't got factors by the morning.

I can now see a C150 at index 2686. I've run 400 @ B1=25e4, I'm starting some curves at B1=3e6.

EDIT: p33 * p118, index 2687 now contains a C157.

1400 @ B1=3e6, no factor. Stopping.
