%N Smallest d such that Mordell's elliptic curve x^3-y^2=d (for positive d) has an integral point in the quadratic extension sqrt(A202057(n)).

%C The existence of such d for each A202057(n) is conjectural following the conjecture in A201278.

%C For x values see A202054.

%C For y values see A202055.

%F a(n) = A202054(n)^3 - A202055(n)^2

%Y Cf. A201278, A202054, A202055, A202057.
