Please consider def H(n,k): return hypergeometric([-k, -n + k], [-k], -1) def T(n,k): return int(H(n,k).n()) def S(n,k): return H(n,k).simplify_hypergeometric() for n in range(8): print([T(n, k) for k in range(n+1)]) print([S(n, k) for k in range(n+1)])
The result: [1] [1] [1, 1] [2, 1] [1, 2, 1] [4, 2, 1] [1, 3, 2, 1] [8, 4, 2, 1] I expected the same result in both cases. Note that both Maple and Mathematika return the first variant, T(n, k), probably indicating a problem in simplify_hypergeometric()?
