(p ≥ 5) can be characterized by its order components
Let G be a finite group, and (p ≥ 3). It is proved that G ≅ M if G and M have the same order components.

Let with and let be the corresponding hyperbolic triangle group. Many papers have been dedicated to the following question: what are the finite (simple) groups which appear as quotients of ? (Classically, for and more recently also for general .) These papers have used either explicit constructive methods or probabilistic ones. The goal of this paper is to present a new approach based on the theory of representation varieties (via deformation theory). As a corollary we essentially prove...
