MATHEMATICA

QuadPrimes[6, 0, 11, 10000] (* see A106856 *) Note: the original QuadPrimes had a bug which could sometimes give wrong answers. This sequence should be checked (unless the coefficient of xy in the quadratic form is zero, in which case QuadPrimes gives correct answers).  N. J. A. Sloane, Jun 04 2014
