Abstract
We prove that every non-elementary hyperbolic group acts with maximal growth on some set such that every orbit of any element is finite. As a side-product of our approach we prove that if is non-elementary hyperbolic, is quasiconvex of infinite index then there exists such that is quasiconvex of infinite index and is isomorphic to if and only if , where is the maximal finite normal subgroup of .
