 OFFSET 0,5 COMMENTS The first row is a signed version of the Euler numbers A000111. Other rows are defined by a(n+1,k) = a(n,k)+a(n,k+1). LINKS A. Randrianarivony and J. Zeng, Une famille de polynomes qui interpole plusieurs suites..., Adv. Appl. Math. 17 (1996), 1-26. See Section 6. EXAMPLE The first few antidiagonals are: 0, 1,1, 1,2,3, -2,-1,1,4, -5,-7,-8,7,-3, 16,11,4,-4,-11,-14, 61,77,88,92,88,77,63, -272,-211,-134,-46,46,134,211,274, ...
