Tom, I'm post-processing L2755A and LA is due to finish in 70 hours.

[QUOTE=fivemack;478607]Sean: I accidentally reserved L3865B, which I think is your fox (since you found the polynomial and did the ECM): I've removed my reservation, could you confirm that you plan to do it in the medium term and I'll put your name on it?[/QUOTE]

Yes, I will postprocess L3865B in the medium term (a few weeks I think).

Taking 5393^71-1 (15e).

That could have been very bad, with only two non-trivial dependencies I think I was very lucky not to have wasted fifty days of compute on my fastest machine.
