I know that Steven has been on this forum in the past, but is probably isn't one of his usual haunts. If you point him to this thread, then he might visit more often.

The difference is in the definition:

The reason for the restriction on the exponent n is simple, without some restriction every prime p would be a generalized Woodall.

so any prime that can be...

I just noticed today that Steven Harvey has posted the list of Generalized Cullens for 100 < b <= 10000. All b < 201 have been searched to n=100000 and all b > 200 have been searched to 10000.

That will save me a little time.

I have a small program that will take all of the primes, then generate a list in the same format that Steven uses for Generalized Woodalls. It will also merge...

I am currently sieving all bases for 101 <= b <= 10000 up to n=10000. That should be done by the weekend. I will start PRP testing in about two weeks. When that is done I'll provided a page for...
