C190_144_125 needs more sieving; density 120 did not build, and density 114 resulted in a 32M matrix.

How about extending Q to 400M?

I've extended Q to 440M, with the intention of getting 550M or so relations; that ought to get you a noticeably nicer matrix.

(do we have records of what ECM was done on this number? p52 feels a little small to be extracting by SNFS at this stage)

18000 curves @B1=110M plus another 8000@B1=260M. Probably should have done more ECM at the t60 level, sorry this one slipped through.

Thanks, this worked as promised. TD 134 built matrix 26.5M in size; 140 did not build. 26M isn't hard, so I'll get to work.
