COMMENT

a(n)=A070474(n) [Proof: n^5-n^3 =0 (mod 12) is shown explicitly for n=0 to 11, then the induction n->n+12 for the 5th order polynomial followed by binomial expansion of (n+12)^k concludes that the zero (mod 12) is periodically extended to the other integers.] [From R. J. Mathar (mathar(AT)strw.leidenuniv.nl), Jul 23 2009]
