Dually, one has the concept of a left X-approximation (or, a X-preenvelope) WebIn [2] the ﬁniteness of GcdZG was proposed as an algebraic characterization of those groups G which admit a ﬁnite dimensional model for EG, the classifying space for proper actions. The Gorenstein dimension of a group G over Q,GcdQG, is the Gorenstein projec- tive dimension of Q as a trivial QG-module.
