Abstract.
The Steinberg module is a certain homology group of the curve complex of a surface considered as a module over the mapping class group of the surface. In this paper we will define the Steinberg module and examine some of its properties. Most notably we will look at a presentation for the Steinberg module and at a proof that it is cyclic.
