Here is a nice poly:

Code:
# norm 1.106296e-11 alpha -7.271427 e 2.253e-10
n: 147998406675517406327680061413386342160268805242427078451900343934549131780622905201645576998223639153399654673028891064447

c5:  3000
Y0: -547802417747206906822973
Y1:  11796075364271
Best poly I found after searching with msieve on 2 cores for 5 hours.

Who wants to take it?

I only had an hour or so to do poly selection (with GGNFS) and started sieving with a poly with e ~2e-010

I currently have about 8M relations. If someone can do it faster, go ahead, otherwise i'll just et it run.

I'll run a few very high level curves.....does someone else want to tackle the NFS if it comes to that? I just had two jobs finish, so my CPUs are open at the moment.
