too good to be true?
Today, someone added what appears to be a new primality test for Fermat numbers:

I think TRex of this forum has claimed a similar result. Approximately half of the possible polynomials for Lucas sequence proofs give N1 tests instead of N+1 tests. This is one such choice. It looks correct, but it's no faster than Pepin's test.
