Nice 3-way split

chris2be8 · 2022-03-18, 17:17

f76_145p1 has built a matrix. ETA about 16 hours.

Downloading the relations took me over 21 hours. Which is annoying.

chris2be8 · 2022-03-19, 16:42

And f76_145p1 is done:

And so is 11p9_251.

I’ll take 7p6_353.

I've hit problems with f76_143m1. Downloadling the relations worked OK, but msieve has rejected all the relations.

When you queued this number, you included the "m" value even though the R1 coefficient was not 1. At some point this was interpreted as meaning R1=1, R0=-m, and these got erroneously added to the .fb file along with the correct values:

Code:

You can see that msieve is using the incorrect rational coefficients. Get rid of those two lines and everything should be fine.

And f76_143m1 has built a matrix. LA should finish in about 46 hours.

I've also updated my script to comment out the m: line provided by phi. Which should stop this happening again.
