C173_785232_11580 have built a matrix of 13.9M with TD=110 (TD=120 failed). Seems that 360M relations of which 280M are unique is a bit too low.

Do you want more Q?

Sorry, that's a really big matrix for that job. I expected to get under 12M for sure. :(

Suggesting a sieving range for Q of 35-235M to generate 445M raw relations.

Please note I also tested the quintic SNFS polynomial (SNFS 267 difficulty) but the yield and speed were disappointing: only 420M raw relations estimated to be produced using the max allowable sieving range for Q of 35-235M, all with greater sec/rel than above at each Q value.
