This doesn't make sense either. Why do you need B? you can simplify it in both sides. If that is true, you just found a method to run the PRP test in half number of iterations than required. This is...

This doesn't make sense. 997 is prime. Is my "reserved task" to test if 997 is prime? or to test if 2^997-1 is prime?

In any case, I can pick ANY B=M, run 250 iterations of B=B^2 (mod 997), give...

Yes, impossible. I just pick a random M and do E/2 iterations from it, to get whatever final F, and send you M and F. I don't give a dime about the first half iterations, as long as your verification...

1. I am reserving Mx for PRP.
2. I generate x random residues in a file, without doing any work, just garbage data.
3. I apply your calculus on my garbage...

That is what he was calling "*drastically* lower". This way, lots of tests that won't cause error in the "aggressive" version, would run a lot slower with the larger FFT. Then you would have to find...
