We partially characterize the rational numbers x and integers n >/0 for which the sum ~--~o k"xk β€’ go n assumes integers. We prove that if ~k=0 k x k is an integer for x = 1 -a/b with a, b > 0 integers and gcd(a,b) = 1, then a = 1 or 2. Partial results and conjectures are given which indicate for wh
