%N Primes p that have Kronecker symbol (p|86) = 1.

%o (PARI) select(p->kronecker(p, 86)==1&&isprime(p), [1..1000]) \\ This is to provide a generic characteristic function ("is_A191051") as 1st arg of select(), there are other ways to produce the sequence more efficiently. - _M. F. Hasler_, Jan 15 2016
