 OFFSET 0,4 COMMENTS Row sums = 2^n. Right border = A152537, left border = A000041. LINKS FORMULA Triangle read by rows, M*Q. M = A027293 as an infinite lower triangular matrix with the partition numbers (A000041) in every column. Q = a matrix with A152537 as the main diagonal and the rest zeros. EXAMPLE First few rows of the triangle = 1; 1, 1; 2, 1, 1; 3, 2, 1, 2; 5, 3, 2, 2, 4; 7, 5, 3, 4, 4, 9; 11, 7, 5, 6, 8, 9, 18; 15, 11, 7, 10, 12, 18, 18, 37; 22, 15, 11, 14, 20, 27, 36, 37, 74; 30, 22, 15, 22, 28, 45, 54, 74, 74, 148; 42, 30, 22, 30, 44, 63, 90, 111, 148, 148, 296; 56, 42, 30, 44, 60, 99, 126, 185, 222, 296, 296, 592; 77, 56, 42, 60, 88, 135, 198, 259, 370, 444, 592, 592, 1183; ... Row 3 = (3, 2, 1, 2) = termwise products of (3, 2, 1, 1) and (1, 1, 1, 2). CROSSREFS Cf.
