%N Number of partitions of n into 4 distinct nonnegative cubes.
%C In other words, number of solutions to the equation n = w^3 + x^3 + y^3 + z^3 with w > x > y > z >= 0. - _Antti Karttunen_, Sep 21 2018

%e For n=540 we have two solutions: 540 = (0^3 + 1^3 + 3^3 + 8^3) = (2^3 + 4^3 + 5^3 + 7^3), thus a(540) = 2. This is the first point where a(n) > 1. - _Antti Karttunen_, Sep 21 2018
