%N Indices of the nonzero terms in expansion of Dirichlet series Product_p (1-(Kronecker(m,p)+1)*p^(-s)+Kronecker(m,p)*p^(-2s))^(-1) for m = 29.
%C Terms seem to be exactly the numbers represented by the indefinite binary quadratic form (1, 7, 5) with discriminant 29 (Lagrange-Gauss reduced (1, 5, -1)). - _Peter Luschny_, Jun 24 2014
