Delyan Something is wrong with Check Program [8] // Problem 1625. Hankel Matrix 8 Oct 2008 06:26

I make matrices from the sequence of Catalan numbers 1,2,5,14,42,132,429,1430,4862,...
Such matrices satisfy all criterion:
1)All numbers are positive integers
2) Determinants of all matrices are equal to 1
But I get WA2
