Talk:Wagstaff prime

From Wikipedia, the free encyclopedia

[edit] what is this list?

That list: 3, 5 7, 11 etc... is that for the exponent p or the Wagstaff prime itself? It says in the article those are the first few Wagstaff primes, but I don't think so... for instance, if 5 was a Wagstaff prime, it would follow that ((2^p)+1)/3 = 5 for some prime p, ie 2^p = 14, which is nonsense... ln(14) isn't even natural.

Those are the indexes, see (sequence A000978 in OEIS). They are themselves prime, which naturally leads to some confusion. The Wagstaff primes themselves are listed in A000979. PrimeFan 22:36, 1 June 2006 (UTC)
