%N Prime divisors of 2^1092-1, listed with multiplicities.
%C Up to now only two primes p such that p^2 divide 2^(p-1)-1 are known (these two are Wieferich primes, see A001220).
%C The sequence is finite with A001222(2^1092-1) = 49 terms; A001221(2^1092-1) = 45. - _Reinhard Zumkeller_, May 14 2010
%C Terms appearing more than once (in fact twice) are 3, 7, 13, and 1093.
