Regarding TD and its influence on the matrix. I accidentally omitted the TD option when doing 9p8_277 so I can compare the default, I think it's 90, and TD 120.
TD default: 21001871 x 21002097 (192 h) TD 120: 19133102 x 19133327 (184 h) TD 130: too few cycles

143__553_17m1 factored
Greg was kind enough to get this number "off the board". The low amount of quality relations at higher Q was diminishing. The high dup rate for an octic was not considered. He used an A100 (40GB) card to solve a 34.8M matrix (TD=100) in under 2.5 hours. The joys of having a souped up laptop. Hehehe BTW, The C233 splits as p79 * p154 per the above.

@bur, please check your gnfs/filter/filter.c to see what DEFAULT_TARGET_DENSITY you have.
