Code:
prp56 factor: 70474838470398166975430111758099027193695120577835592463
prp166 factor: 1468625064688653877156370107262001424005899973431239516345520907697237497922202126994319199847205557550897168197493851748285511354981016285930910443660224192500563923
The rational side resulted in 320166800 raw / 253751246 unique

The algebraic side resulted in 290251467 raw / 232270944 unique

The combined data file had 611639172 raw / 351058209 unique which (finally) built a matrix at TD=100. Higher densities failed. A snipped log file for the combined data file is attached. There were many errors in the filtering stage, not sure if it was corrupt data or something else. I'll hang onto the full log files for now. PM me if you are interested in them.

And yes, a p56 is really annoying...

That's my cue.

I'll start with C179_128_87, which is he first number without a listed PP-er. frmky, can you confirm that you haven't taken this and/or your numbers are listed as reserved?

Bump.

Certainly. I’ve got a few 15e in the oven (ECM) but I’ll hold those back as well until we catch up on that siever. It’s the usual tension between feeding the grid vs. backlog postprocessing.

This one looks like it'll take a week or so (plus time 'wasted' by me using the computer), while my 'server' is nearly done with its current batch of GIMPS work, so I'll also move that box to 14e postproc for a bit.

To feed it, I'll take C167_6228362269_23.
