%N Prime numbers congruent to 1, 16 or 22 modulo 39 neither representable by x^2 + x*y + 10*y^2 nor by x^2 + x*y + 127*y^2.
%C Brink showed that prime numbers congruent to 1, 16 or 22 modulo 39 are representable by both or neither of the quadratic forms x^2 + x*y + 10*y^2 and x^2 + x*y + 127*y^2. A325075 corresponds to those representable by both, and this sequence corresponds to those representable by neither.

%e Regarding 61:
%e  61 is a prime number,
%e  61 = 39 + 22,
%e  61 is neither representable by x^2 + x*y + 10*y^2 nor by x^2 + x*y + 127*y^2,
%e  hence 61 belongs to this sequence.
