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)

I rewrote the definition to make clear the difference between the wagstaff primes and the prime exponents of 2 in the numerator. I also wrote out explicitly why 3,11,and 43 are wagstaff primes. some connections to other areas would help fill out the article.Essap 23:16, 7 May 2007 (UTC)essap
