Sorry about that. Thank you for the runs in the 14.0M range.

I've attached another file for the 1.6M range; no one has worked on the exponents with no factor in this range for a while, so these...

I will definitely do this if there are requests for more files.

Is there demand for more files? I have a few ideas for shorter tasks that would still be useful for the <20M project.

You're stuck on thinking of factors as f = 2kp+1.

The factor is: f = 105040117068459648578879
The factor+1 is: f+1 = 105040117068459648578880 = 2^6 × 3 × 5 × 13 × 47 × 2377 × 5743 × 5953 × 2...
