Sieving is fast per q though, approximately 180 s / 10,000 q (usually 600 s). Due to the low rels/q yield that was initially 25 rels / s, now it's down to about 10 rels / s. Max, if this is too offtopic, let me know, then I'll take that elsewhere. But maybe it's interesting for other SNFS jobs of your numbers?

Line 56 (6,7) complete by SNFS. Required rather more relations than I was expecting (29.7m raw worked, 29.3m raw didn't) and about 1100 threadhours, so three or four days on a notveryidle i97940X.
14e siever, average 1.6 to 1.9 million relations per millionQ Not quite sure what to work on next  I can probably do a 180digit GNFS in two weeks, I have done quartic SNFS of difficulty 250 for the Fibonacci numbers but that took 150k threadhours which is getting quite substantial, especially when 120 of my threads are still waiting for an electrician.

Thank you for finishing it, fivemack! > Not quite sure what to work on next Line 99 (4, 9)  two SNFS jobs got released by thyrex.

Should I continue with SNFS on line 103 or something else a higher target?

Line 103 SNFS sounds great for me, if you are up for the complexity of it. It is a target as it opens a new point on the plot, last composite. Do you need polys generated for it? I am marking the sheet for you.

a2 was the best poly, sieving now. Getting a little over 2 rels/q average so far with a poly very highly skewed toward rational and the 14e siever.
