Here's a poly:

I can start the NFS tonight (12 hrs from now or so) if no-one else has volunteered by then, and if ECM is good.

In the process of running 2k@44M (Edit: done). I can't do NFS by myself, would take too long on my single home machine, but I can throw in a few relations if you like.

I'm doing 1k @ 44M, so by tonight we should be done with ECM.

I can take it solo - but thanks for the offer.

I'm ~65 curves short of 2K@12M, so we're just a bit past t45.

i3027 @ c129

Starting 1K@4m
Actually, better make that 2K
Anybody feel like going for ECM factorization only?

I'd rather try a QS factorization than that :smile:

One of my two ECM runs on line 3027 produced this gem:
[code]Run 153 out of 2000:

Second largest factor is 96.13% of B1 and largest factor is 59.85% of B2.

Nice! I was halfway through poly select - will happily kill it.
