Questions about P+1 Strategy

Let's assume I dedicate G ghz-days of computational effort to run a P+1 curve on a Mersenne number. When I do this, mprime/prime95 reports a probability of finding a factor as X%.

If I then...

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...

Many thanks, George! A quick look turned up an anomaly: https://www.mersenne.org/report_exponent/?exp_lo=14049143&full=1 lists B1,B2 bounds that aren't reflected in the new table.

These exponents had a factor found (almost certainly through trial factoring); once that first factor was found, no further work (e.g. P-1) was done on them. Now that we have the sub-project effort...

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.

The geometric mean (the square root term) gets you a value intermediate to the ECM and P-1 values for B1 and the other term might help with some degenerate cases where the P-1 bounds might be less...

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...

The worktodo line below requires 3.6 Gb of RAM on my machine; I would guess that a larger B1 would imply a larger B2 and require more RAM.
