Yep, from this:
Code:
900180  267. sz 103 2^3 * 3 * 5^3 * 661
to this:
Code:
900180  302. sz 114 2^3 * 3 * 5
So, 11 digits in 35 lines, or 176 digits by 500 lines.....

Nope, not the DB workers. That was 5-6 cores of an I7 knocking those out. I'll take credit for everything that Serge said was "done already too". I was working these down and reporting statuses every 2-3 days. The DB workers do not do factors C>=95. I wasn't reserving because there had been no interest and I was planning on a status later today. It's odd that 4 different people all of a sudden got interested right at the end. lol

Oh well, it's mostly done now. I'll report one final status later today for historical reference, for what it's worth. :-)
