I was reading a paper on hyperbolic geometry and was unable to understand the following
Gluing opposite faces of the dodecahedron by a three-fifths twist we obtain a closed hyperbolic 3-manifold called the Seifert-Weber dodecahedral space. The group of face-pairing transformations generate a Kleinian group such that the quotient of hyperbolic 3-space by this group is the Seifert-Weber dodecahedral space.
I am unable to produce a proof of this. Some help or even a sketch of the proof would be appreciated. Also, can somebody suggest a good reference for things of this kind.
