[QUOTE=jyb;519864]38160408950501_17m1 needs more sieving. Over 35% of the relations are duplicates, and msieve doesn't get very far in filtering before it complains. I'd probably add another 40M.

[B]Done.[/B][/QUOTE]

Well that additional 40M range of special-q resulted in only 26M additional relations. And of those, 14M were duplicates, so we only ended up with 12M more unique relations. Unsurprisingly, msieve is still unhappy with what we've got.

I would suggest more sieving, but at this point the returns are diminishing so fast that it's hard to know what to do. I'll defer to those who have more expertise with this sort of situation than I do.

I'll take it and finish off the sieving locally at the low end. I just started another similar job (GNFS-180) and the solve time is about four weeks at TD=132. It may be a while before 71316922984999_19m1 gets off the board.

71316922984999_19m1 should finish up on Wednesday.

I would sieve 15-20M on 15e offline, and hope I get enough relations to build some sort of matrix, even if it's density 80 or 75.

Oh, sorry. When I looked at the status page I thought you only had one number and that was what you were talking about.

I'll still take 38160408950501_17m1 and complete it locally.
