(Magma) [p: p in PrimesUpTo(653) | KroneckerSymbol(p, 86) eq 1]; // Vincenzo Librandi, Sep 11 2012
(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
