Yes, useless.

I'm not even sure it will be useful to the let's get number of unfactored exponents below 20M crowd.

Caveat: I'm not a P+1 expert.



When we do P-1 on Mersenne numbers factors are of the form f=2kp+1, thus we find a factor f when k=(f-1)/(2p) is B1/B2-smooth.

With P+1, factors are of the...

P+1 stage 1 would be a little less than twice as slow as P-1 stage 1.
P+1 stage 2 would be a little faster than P-1 stage 2.

If prime95 supported P+1 it might produce output like this for a 2/7...

There was code to expire PRP-CF assignments more than 30 days old. It was broken.
Hopefully fixed, the stored procedure will run tonight. I did change it to 60 days.
