Taking GC_5_332.

[QUOTE=fivemack;370938]I'll take L1247 - the sieving isn't quite complete, so I'll download when 2W770 has finished, which should be Sunday early-morning[/QUOTE]
This has fewer relations than I expected. Let me know if you would like me to extend the sieving a bit.

That would be kind: would you mind going for 240M relations? I have plenty of aliquot-sequence numbers to keep the cores busy, and whilst the 210M relations do make a matrix, it's a 17.1M matrix and would take probably ten days.

(I think 240M relations is probably a sensible target in general for these 260-difficulty SNFS)

[/code][/QUOTE]Curious. That's three successive p72 factors.

fivemack, If you want I can do L1247 for you and you can get the credit as well. I use the server from the lab so free electricity.
