Abstract:  In 1891, A. Hurwitz reduced a topological question to a counting problem:  In how many ways can one factor an n-cycle into n-1 transpositions?  His answer, n^{n-2}, has many proofs.  We will discuss one of them, and then describe some deformations of Hurwitz’s formula where a parameter q is added to the mix.
