 OFFSET 1,3 COMMENTS Row sums = A069735: (1, 3, 2, 5, 2, 6, 2, 7,...). T(n,k) = 2 if k is even and divides n, 1 if k is odd and divides n; 0 otherwise. LINKS FORMULA Triangle read by rows, A051731 * A000034 * 0^(n-k), 1<=k<=n; where A051731 = the inverse Mobius transform and A000034 = (1, 2, 1, 2, 1, 2,...). EXAMPLE First few rows of the triangle are: 1; 1, 2; 1, 0, 1; 1, 2, 0, 2; 1, 0, 0, 0, 1; 1, 2, 1, 0, 0, 2; 1, 0, 0, 0, 0, 0, 1; ... CROSSREFS Cf. A051731, A000034, A069735.
