In this article, we start from the combinatorial version of the coupon collector problem, in order to generalize it to the infinitely generated groups. We introduce it analogously to the waiting time in order to complete an n-collection and then after, we establish the graph invariance associated with a finitely generated group. We compute the average of this waiting time for monogenic and free groups.
