Maximal virtual schottky groups: explicit constructions

A Schottky group of rank $g$ is a purely loxodromic Kleinian group, with non-empty region of discontinuity, isomorphic to the free group of rank $g$.A virtual Schottky group is a Kleinian group $K$ containing a Schottky group $\Gamma$ as a finite index subgroup. In this case, let $g$ be the rank of...
