 OFFSET 1,4 COMMENTS Row sums = A125275 starting with offset 1: (1, 2, 7, 31, 162, 968,...). Left border = A000108, right border = A125275. Sum of n-th row terms = rightmost term of next row. LINKS FORMULA A147294 = Triangle A039599 * (A125275 * 0^(n-k)); where (A125275 * 0^(n-k)) = an infinite lower triangular matrix with A125275: (1, 1, 2, 7, 31, 162,...) as the main diagonal and the rest zeros. EXAMPLE First few rows of the triangle = 1; 1, 1; 2, 3, 2; 5, 9, 10, 7; 14, 28, 40, 49, 31; 42, 90, 150, 245, 279, 162; 132, 297, 550, 1078, 1674, 1782, 968; 429, 1001, 2002, 4459, 8463, 12474, 12584, 6481; 1430, 3432, 7280, 17836, 39060, 71280, 100672, 97215, 47893; ... Row 4 = (5, 9, 10, 7) = termwise products of (5, 9, 5, 1) and (1, 1, 2, 7) CROSSREFS A125275, Cf.
