%N Positive fundamental solution x(n) of the generalized Pell equation X^2 - D(n) Y(n) = 2 with D(n) = A261246(n).
%C For the corresponding positive fundamental solution y(n) see A261248(n).
%C [x(n), y(n)] gives the positive proper fundamental solution for D(n) = A261246(n), for n >= 1.
%C See the comments on A261246 for this generalized Pell equation.
%e See A261246.
