f45_152p1 had built a matrix. About 77 hours remain to solve it.

I do not know why there seems to a problem with sieving C172_434040_3112. I test sieved up to Q = 200M and there should be about 260M relations for the Q range (40-130M) that I chose. Sieving is almost complete and there are only 150M relations. Any thoughts?

Results from 5k test sieves:

Q Relations
20M 8161
50M 13218
100M 15524
150M 16651
200M 15336

Add another 70M Q (130-200M)?

Yes, I believe I’ve located the problem. In your original post, you had a line “lss:0”, but it should read “lss: 0”. Msieve is apparently ignoring this line in its current erroneous form and is sieving on the rational side.

I should have caught this typo but did not. My apologies.

Moving forward, I can

A. Fix the typo and see what happens.
B. Ignore the typo and extend Q further
C. Let this job finish and start another job called C172_434040_3112a with the correct syntax and sieve on the algebraic side albeit over a smaller range. You can download both data files, combine them and proceed with LA.

A is the fastest option, but there’s a chance Greg will have to intervene if something breaks.

Any suggestions? Greg?
