In this paper, we study the action of , the identity component of the group of homeomorphisms of an -dimensional manifold with an -free action, on another manifold of dimension . We prove that if is not an -homology sphere, then for a homology manifold such that the action of on is standard and on is trivial. In particular, for a sphere, any nontrivial action is a generalization of the “coning-off” construction.
