My search is continuing. I'm working from A5=2e6.
Apparently a job this size has 30 slices, so overlapping ranges wouldn't be much of a problem.

Curtis, what settings are you using for a C175?

That's a good point.
We already see the nice line that log(e-score) falls on when plotted against log(log(n)).
So I guess this kind of table is already "just for fun".

Some of the very smallest ones are missing due to the way MultiSieve works.

I have some factors, should anyone want to verify.
