I changed from 29-bit to a 30-bit job because of the yield but forgot about the higher relations requirement. As info, this number should go to Q=46M based on the below.

Trial sieving 5K blocks, on 14e siever, on the rational side:

Code:
Q = 25M: 9336 rels
Q = 85M: 6407 rels
Q = 145M: 5607 rels
Q = 205M: 4848 rels
Q = 300M: 4384 rels
The algebraic side might be worth sieving in parallel, as it seems to yield about 15% fewer relations (7902 vs. 9336 at Q = 25M).
A note on difficulty: The SNFS difficulty of this composite number is 267.00-digit.

also note that mfba is 66 for a 32 bit job, which doesn't make sense and likely wastes cofactorization effort.

A SNFS difficulty of 267.00 needs the 15e siever - 14e would be very inefficient.

mfba and mfbr are usually 2x or 3x lpba/lpbr (or that -1).

Can you rerun some trial sieving with these corrections?

This C160 might make a nice benchmark dataset (per my side-chat with xyzzy). Could you please post matrix size as soon as you have it? If it's 6-7M, I think Mike (and I) may grab the dataset.

That can’t happen until Greg unjams 14e. Not sure why it went sideways but hoping we have WUs soon.

Eta: Now fixed.
