Title: (Joint seminar with Groups and Dynamics Seminar) Distinguishing certain triangle groups by their finite quotients

Abstract: We prove that some arithmetic Fuchsian triangle groups are profinitely rigid in the sense that they are determined by their set of finite quotients amongst all finitely generated residually finite groups. These include the (2,3,8) triangle group.
