Let n and k be fixed positive integers. A collection C of k-sets of [n] is a completely separating system if, for all distinct i, j?[n], there is an S?C for which i?S and j?S. Let R(n, k) denote the minimum size of such a C. Our results include showing that if nk is a sequence with k?nk?k1+? for every ?>0, then[formula]
