I'll take 127^95 + 95^127 cofactor from the 14e queue.

I forgot to add target_density to the command line, and produced a 21.8M matrix at default density. I re-ran the filtering with TD = 140, and produced the identical matrix!

I realized that meant the dataset was oversieved, so I reduced to 470M relations (from initial 495M) and ran again. This produced a 20.4M matrix at density around 100; reducing to 450M rels produced 19.7M matrix at density 125. This matrix is forecast to take 80-100 hr longer than the original matrix, so I'm solving a 21.8M matrix at density 67, forecast to take 25 days or so.

Matrix-building took 8005MB, while the solving step is logged at 6500MB while top claims 7.6g used.

Taking C193_143_93. Anticipating it will take a couple of months.

39.06M matrix at density=128 started on 6 threads i7-5820K, ETA about six and a half weeks from now (second half of May)
