Surfaces,of regular solids up to similarity by the number of edges of each face and the number of faces meeting at each vertex. It should be clear that we have no hope of classifying topological spaces up to homeomorphism, or even up to homotopy equivalence. We can, however, give a complete classification of closed surfaces.

Simplicial Homology,he underlying complex, making it ideal for studying questions which are essentially two-dimensional (say distinguishing between two surfaces), but leaving it impotent in the face of a problem such as showing that S. and S. are not homeomorphic.
