%N Triangle, antidiagonals of an array generated from A130460.
%C Rows tend to the factorials: (1, 1, 2, 6, 24, ...). Row sums = A130476: (1, 2, 3, 5, 8, 15, 28, 61, 132, ...).
%F Let A130460 = M, an infinite lower triangular matrix and V = [1, 1, 1, ...], the first row of an array. Perform M * V = second row, ...; (n+1)-th row = M * n-th row. The triangle = antidiagonals of the array.
%e The array =
%e 1, 1, 1, 1, 1, 1, ...
%e 1, 1, 2, 3, 4, 5, ...
%e 1, 1, 2, 6, 12, 20, ...
