Abstract
Let G be a nonelementary subgroup of Isom(H n). In this paper we prove that if G contains elliptic elements and dim(M G) is even, then G is discrete if and only if WY (G) is discrete and every nonelementary subgroup of G generated by two elliptic elements is discrete. We also describe an example to show the assumption on dim(M G) is necessary.
