COMMENTS
| Presumably this is the same as Primes congruent to 1 mod 24. - N. J. A. Sloane (njas(AT)research.att.com), Jul 11 2008.
Above checked for all terms up to 2 million, using the Mathematica program QuadPrimes[1,0,24,2000000]==Select[Range[1,2000000,24],PrimeQ] - Vladimir Joseph Stephan Orlovsky (4vladimir(at)gmail.com), May 18 2011.
Discriminant=-96. See A106856 for more information.
Also primes of the forms x^2+48*y^2 and x^2+72*y^2. See A140633. - T. D. Noe (noe(AT)sspectra.com), May 19 2008
