%N A157437 Primes congruent to 1, 5, 7, or 11 modulo 24.
%C A157437 Also, primes p that divide A085606((p-1)/2) = ((p-1)/2-1)^((p-1)/2) - 1. Primes p such that p^2 divide A085606((p-1)/2) are listed in A157438.
%C A157437 Also, primes p>3 such -6 is a square modulo p. - _Max Alekseyev_, May 30 2009
