A051731 = the inverse Mobius transform and (A001318 * 0^(n-k)) = an infinite lower triangular matrix with A001318 (1, 2, 5, 7, 12, 15, 22,...) in the main diagonal and the rest zeros. EXAMPLE First few rows of the triangle = 1; 1, 2; 1, 0, 5; 1, 2, 0, 7; 1, 0, 0, 0, 12; 1, 2, 5, 0, 0, 15; ... CROSSREFS Cf. A051731, A001318, A079248.
