 OFFSET 0,4 COMMENTS Row sums = A006318. Left border = A001003. Sum of n-th row terms = rightmost term of next row. LINKS FORMULA Triangle read by rows, T(n,k) = A001003(n-k)*A006318(k-1) with A006318(-1)=1. (corrected by R. J. Mathar, Jul 19 2016) EXAMPLE First few rows of the triangle = 1; 1, 1; 3, 1, 2; 11, 3, 2, 6; 45, 11, 6, 6, 22; 197, 45, 22, 18, 22, 90; 903, 197, 90, 66, 66, 90, 394; 4279, 903, 394, 270, 242, 270, 394, 1806; ... Row = (11, 3, 2, 6) = termwise products of (11, 3, 1, 1) and (1, 1, 2, 6) = (11*1, 3*1, 1*2, 1*6). CROSSREFS Cf. A001003, A006318.
