 OFFSET 0,2 COMMENTS Right border = the partition numbers, A000041. LINKS FORMULA A140207 * A000012 as infinite lower triangular matrices. EXAMPLE First few rows of the triangle are: 1; 2, 1; 4, 3, 2; 7, 6, 5, 3; 12, 11, 10, 8, 5; 19, 18, 17, 15, 12, 7; 30, 29, 28, 26, 23, 18, 11; 45, 44, 43, 41, 38, 33, 26, 15; ... n-th row of the triangle = partial sums n-th row terms of triangle A140207 starting from the right. Example: row 3 = (7, 6, 5, 3), since row 3 of triangle A140207 = (1, 1, 2, 3). CROSSREFS Cf. A000041, A000070 (first column), A141156 (row sums), A140207.
