%N A296937 Rational primes that decompose in the field Q(sqrt(13)).
%C A296937 Is this the same sequence as A141188 or A038883? - _R. J. Mathar_, Jan 02 2018
%C A296937 From _Jianing Song_, Apr 21 2022: (Start)
%C A296937 Primes p such that Kronecker(13, p) = Kronecker(p, 13) = 1, where Kronecker() is the Kronecker symbol. That is to say, primes p that are quadratic residues modulo 13.
%C A296937 Primes p such that p^6 == 1 (mod 13).
%C A296937 Primes p == 1, 3, 4, 9, 10, 12 (mod 13). (End)
