The OEIS Foundation is supported by donations from users of the OEIS and by a grant from the Simons Foundation.

 Please make a donation to keep the OEIS running. We are now in our 56th year. In the past year we added 10000 new sequences and reached almost 9000 citations (which often say "discovered thanks to the OEIS"). Other ways to donate

 OFFSET 1,1 COMMENTS 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. Also, primes p>3 such -6 is a square modulo p. - Max Alekseyev, May 30 2009 Rational primes that decompose in the field Q(sqrt(-6)). - N. J. A.
