%N Following triangle is based on Pascal's triangle. The r-th term of the n-th row is product of C(n,r) successive integers such that the product of all the terms of the row is (2^n)!. Sequence contains the triangle read by rows.
%C The leading diagonal contains 2^n. The second column terms are (n+1)!.
%e Triangle begins:
%e 1
%e 1 2
%e 1 6 4
%e 1 24 210 8
%e 1 120 332640 32760 16
%e ...
%e The row for n = 3 is
%e 1 3 3 1
%e 1 (2*3*4) (5*6*7) 8 or (1 24 210 8)
