%N Let Py(n)=A000330(n)=n-th square pyramidal number. Consider all integer triples (i,j,k), j >= k>0, with Py(i)=Py(j)+Py(k), ordered by increasing i; sequence gives k values.
%C i values are A053719 and j values are A053720.
%e Py(55) = 56980 = Py(45) + Py(42); Py(70) = 116795 = Py(69) + Py(24);
%Y Cf. A000330, A053719, A073720.
