msieve svn984 seems to stop after finding one factor even when the number has several.

Taking 7+4.293

I'll take 8543_61_minus1 once it is done sieving, assuming it is still available. Thanks.

116 hours for 13.1M matrix on i7/4790K -t4

fivemack · 2015-07-09, 16:44

I'll see if I can do 5297_67_minus_1 over the weekend

Edit: no; matrix is currently 18.7M at density=100, which is a bit impractical; asked for more sieving.

Really this number was too big to queue at 14e.

Second edit: now running, matrix is 17.0M at density=110, ETA 237 hours on four cores i7/4770K (i.e. evening of 22 July)
