 OFFSET 0,2 COMMENTS Sum of n-th row terms = A000521(n-1). LINKS FORMULA Antidiagonals of a table, A161361^2, where A161361 = the convolution square root of A000521. EXAMPLE First few rows of the triangle = 1; 372, 372; 29250, 138384, 29250; -134120, 10881000, 10881000, -134120; 54261375, -49892640, 855562500, -49892640, 54261375; -6139293372, 20185231500, -3923010000, -3923010000, 20185231500, -6139293372; ... The multiplication table by rows: .......1,.......372,.....29250,... .....372,.....38384,..10881000,... ...29250,..10881000... .-134120... ... Take antidiagonals such that row 2 = (29250, 138384, 29250), sum = 196884 = A000521(2). CROSSREFS Cf.
