I did a few more steps through the workers.

Keep your fingers crossed, while the 3 is raised to a higher power we have a better chance of getting rid of it, with the right factorization. The growth rate is going to start hurting pretty quickly, though.....

The c107 is done (the p35 could have been found with a little more ECM) and in the database.

Currently line 2401, with a c132 which I babysitted in the database queue up to 1/3 of the 40digit level. Will continue tomorrow if it is not finished by then. I think you can start searching for a poly. H.

I did babysit it a little this afternoon. I've been running 60 curves with B1=11M, no luck.

It's time to start thinking about a new team sieve.

I am NFSing the c99 it is on now.

The guide has changed to 2^6*3^2.

p43 with B1=3M - nice!
