What happen to your dataset? The first couple runs identified 314M unique relations. The one you finally settle on had 217M unique relations. I'm surprised you could build a matrix with that.

I used remsing ... note that the number of relations after singleton removal is much more similar on the later runs

Code:

pre-remsing
Wed Aug 28 15:20:03 2019  reduce to 162937239 relations and 154017924 ideals in 21 passes

post-remsing
Thu Aug 29 01:16:22 2019  reduce to 162476029 relations and 154147535 ideals in 20 passes

I don't quite understand why these figures differ at all

The number of cycles is

Code:

td=70, no remsing
Wed Aug 28 16:53:05 2019  weight of 34429964 cycles is about 2410119182 (70.00/cycle)

td=102, remsing
Thu Aug 29 03:17:53 2019  weight of 29754382 cycles is about 3034968697 (102.00/cycle)

which is about the drop from density-70 to density-102 that I would have expected

Ah, there was a bug in my hex parser which was corrupting the last prime read on each line. I've fixed that and have more confidence in the newer version of remsing, at
