Congrats. Try adding PRPBase=n to prime.txt.

Still need to do some (slow) independent check with PFGW. Ugh!

Congrats.

If I were you, I would run:

Code:
./pfgw64 -tc -q"(2^3464473-1)/604874508299177"
to get a fermat+lucas PRP test done.

Thanks. That worked (well, it isn't obvious that it worked, so I tried it first on a composite number).

I have already submitted the PRP to the Top list after passing b=5,7 tests, but I will run this as well. The problem is that PFGW doesn't have suspend/resume for these tests, so I'll have to be careful not to shutdown my laptop or interrupt the test in anyway while it runs. Probably will take the better part of a day (or more) to run it, since PFGW uses the generic FFT for them.

I've just found:

M488,441 = 61543567 x 30051203516986199 x PRP-147012

Anyone up for making: a) a website or b) a codebox on the first post to show what Mersenne numbers have been "fully factored" (PRPs anyways)?

I'm a bit unfamiliar with Probable Primes. How Probable is Probable? Is there a realistic chance that any of the PRP's for the "fully factored" Mersennes are actually composite?

There is a more realistic chance you will be hit by lightning whilst simultaneously being hit by a meteor whilst simultaneously experiencing an earthquake of magnitude 9.9 on Friday the 13th at 06:06:06 in the morning.
