| Sep 20, 2015 at 17:13 | comment | added | Lee Mosher | Just a comment: One reason linear groups arise naturally in this context is because of Serre's Theorem which says that if $G$ is a finite subgroup of $MCG(S)$ then the restriction to $G$ of the canonical homomorphism $MCG(S) \to Aut(H_1(S;A))$ is injective, as long as the coefficient group $A$ has no 2-torsion. If you just want a list of examples this comment is not particularly relevant, but if you want a proof then it might be more relevant. | |
