Carlos - try moving the R0 and R1 lines below the polynomial. All my successful example files seem to be structured that way. Parser issue maybe?

That did the trick. Gonna leave filtering during the night with td=130, hope it reaches the LA phase.

Mike - I’m grinding through LA now, should be done ~1 Feb if that’s OK with you.

Unreserving since LA didn’t start with td=130, 120 and 110. Lost 12 hours with this.

Gonna go for one last shot at td=95.

461M raw relations, 355M unique. TD=134 produced a 26.4M matrix, which required around 600 hr on 6 threads of a mostly-idle i7-5820. Msieve used ~13GB of 16 installed, so this is close to the biggest project I can personally handle.
Factors *not* reported to factordb, as I don't know where to put them.

I’ve added your factors to factordb and next step is to send an email to marin dot mersennus at gmail dot com

BTW, L2755A LA underway.

Just type I1327 into fdb. I is for Fibonacci numbers, F for Fermat numbers.

Taking L2645A next.
