Nice result. W_816 is just beginning the filtering here. 168.5M uniq relations, 53.2M dups.

15.1M matrix with td=110 (120 didn't build). ETA 320 hours on an AMD Phenom(tm) II X6 1090T using 6 threads and 6.9G of 8G available RAM.

It only just fits and I'm going to have to purchase a bigger system for running jobs any bigger than this.

Well, I've started the linear algebra for 114!+1, on four cores of i7/4770K

ETA for the 26.2M matrix (made with density 120 from 291.6M unique relations and 277.2M unique ideals) is 687 hours, so towards the end of May, and it's taking something like 14 gigabytes of memory - fitting about as snugly in my computer as xilman's matrix is in his.
