WebFirst, observe that every von Dyck group Λ contains a closed surface subgroup Γ of finite index. I will consider only the case when the genus is ≥ 2 since virtually abelian case is much easier. Then, being a closed surface group, Γ is isomorphic to a cocompact arithmetic subgroup Γ ′ of O ( 2, 1).
