LA took almost a month! A long slog but it was satisfying in the end.

I have the log file if anyone wants it.

A bit of a disappointing prp56:

A definite ECM miss......

ETA F1391
 

[B]F1391[/B]
TD=120 failed in full merge stage, but TD=115 produced a very doable 16M matrix:
[code]
linear algebra completed 58438 of 16098485 dimensions (0.4%, ETA 199h37m)[/code]

A p56 is indeed somewhat disappointing for a number whose SNFS difficulty is such that it should have received at least several t55 ECM work (2/9 of SNFS difficulty rule of thumb hints at t60). I thought Fibonacci and Lucas numbers had received a suitable amount of ECM work ?
Of course, we all know that ECM is a probabilistic algorithm.

Yep. ECM MISS != FAILURE IN DUE DILIGENCE
