COMMENTS

Presumably this is the same as primes congruent to 1 mod 24. - N. J. A. Sloane, Jul 11 2008. Checked for all terms up to 2 million. - Vladimir Joseph Stephan Orlovsky, May 18 2011.

Discriminant=-96.

Also primes of the forms x^2+48*y^2 and x^2+72*y^2. See A140633. - T. D. Noe, May 19 2008
