 OFFSET 0,4 COMMENTS Row sums = A136574. Right border = 2*n! - 1 = A020543: (1, 1, 3, 11, 47, 239, 1439,...). LINKS FORMULA (A000012 * A136572 + A136572 * A000012) - A000012, as infinite lower triangular matrices. Triangle read by rows: n-th row = (n+1) terms of n! + (k! - 1), k = 0, 1, 2,...; where the sequence (k! - 1) = A033312: (0, 0, 1, 5, 23, 119, 719, 5039,...). EXAMPLE First few rows of the triangle are: 1; 1, 1; 2, 2, 3; 6, 6, 7, 11; 24, 24, 25, 49, 47; 120, 120, 121, 125, 143, 239; 720, 720, 721, 725, 743, 839, 1439; ... Row 4 = (24, 24, 25, 29, 47) = 5 terms of (24, 24, 24, 24, 24) + (0, 0, 1, 5, 23), where A033312 = (0, 0, 1, 5, 23, 119, 719, 5039,...). 5040, 5040, 5041, 5045, 5063, 5159, 5759, 10079; ... CROSSREFS Cf. A136574, A020543.
