%N Conductor of the elliptic curve y^2 = x^3 + n.
%C The discriminant of the elliptic curve y^2 = x^3 - n is -432*n^2 and the rank is A060950(n).
%C a(n*t^6) = a(n) for all t since the elliptic curve y^2 = x^3 + n*t^6 can be written as (y/t^3)^2 = (x/t^2)^3 + n, and the conductor is an invariant of elliptic curves.
%C Conjectures: (Start)
%C (i) a(27*n) = A356731(n) for all n.
%C (ii) a(n) is divisible by 36, and a(n) = 36 <=> n is a sixth power, a(n) = 108 <=> n is 4 times a sixth power, a(n) = 144 <=> n is 27 times a sixth power; moreover, it seems that a(n) is divisible by 36*n^2 if n is squarefree. (End)
