%N Numbers whose cube is of the form a^5 + b^5 - c^5 with a >= b > 0 and c not in {a,b}.

%C Otherwise said, d-values of nontrivial solutions to a^5 + b^5 = c^5 + d^3.

%e 144^3 = 192^5 + 156^5 - 204^5,

%e 3969^3 = 126^5 + 126^5 - 63^5,

%e 4114^3 = 143^5 + 121^5 - 110^5,

%e 4608^3 = 1536^5 + 1248^5 - 1632^5, ...
