I finished the ranges 17.6M and 17.8M. Now they have 4000 exponents with known factors.

I will continue with the range 17.1M.

I want to reserve 17.6M, 17.7M and 17.8M.

The range 17.1M requires extra TF that I cannot perform because I do not have a powerful GPU.

Change in the tool to find P-1 done with the worst bounds

I found that when the exponent is less than 10M, you can see Mersenne numbers with probabilities that have been factoring using P-1 from 0% to 19.9%.

If you enter a range of exponents greater than...
