%N A249688 a(n) = n-th Ramanujan number A000594(n), squared.
%C A249688 For the functional equation for the Dirichlet series f(s) (for Re(s) > 12) of a(n) see the Hardy reference, p. 180, (10.14.3) or (10.14.4) with (10.14.5). It is, with Phi(s):= (2*Pi)^(-2*s)*Gamma(s)*Gamma(s-11)*Zeta(2*(s-11))*f(s), Phi(s) = Phi(23-s). - _Wolfdieter Lang_, Feb 09 2017
