I'm running a full CADO poly select on your number; I expect a result in about 24hr. I'll test-sieve and post the new job before I go to sleep Monday night.

cownoise says skew 54753925 score 1.240e-13. I left the skew as CADO generated it. This poly scores about 25% higher than the original candidate.

I suggest Q from 25-145M for ~290M relations:
Test-sieve ranges are 1kQ

Code:

#Q=30M	3580 rels, 0.225 sec/rel
#Q=50M	3130 rels, 0.248 sec/rel
#Q=70M	2401 rels, 0.275 sec/rel
#Q=90M	2279 rels, 0.308 sec/rel
#Q=110M 2329 rels, 0.322 sec/rel
#Q=130M 2010 rels, 0.336 sec/rel

test-sieve of 1kQ ranges on the -r side suggest Q from 20-165M should yield ~320M relations:

Code:

Q=20M	3040 rels, 0.246 sec
Q=40M	2703 rels, 0.257 sec
Q=60M	2255 rels, 0.306 sec
Q=80M	2080 rels, 0.321 sec
Q=100M	2197 rels, 0.306 sec
Q=120M	2135 rels, 0.322 sec
Q=140M	1894 rels, 0.358 sec
Q=160M	2016 rels, 0.376 sec

The queue is getting a bit long, so I cut 5MQ off to conserve resources. I'll still get a matrix just fine, I'll just have to wait for nearly-all relations to come in. We should consider trying to conserve Q-ranges in the short term to get more jobs sieved, especially since we have more matrix-solvers than jobs.
