%N Natural number transform of Aitken's triangle.
%C Right border (1, 4, 15, 60, ...) = n*B(n); left column (1, 2, 6, 20, ...) = A052889, n*B(n-1). Row sums = A127741, (n+1) * A005493, where A005493 = row sums of Aitken's triangle.
%F A127648 * A011971 as infinite lower triangular matrices, where A127648 = [1; 0,2; 0,0,3; ...]. (n+1) * each row term in Aitken's triangle.
%e First few rows of the triangle:
%e 1;
%e 2, 4;
%e 6, 9, 15;
%e 20, 28, 40, 60;
%e 75, 100, 135, 185, 260;
