Originally erroneously named "Primes that are not squares mod 14". - M. F. Hasler, Jan 18 2016
From Jianing Song, Nov 21 2019:
Primes congruent to {11, 17, 29, 31, 33, 37, 41, 43, 47, 51, 53, 55} mod 56.
Rational primes that are remain inert in the field Q(sqrt(-14)). (End)
Primes p such that the Legendre symbol (-14/p) = -1, i.e., -14 is not a square modulo p. - Jianing Song, Oct 23 2024
