Abstract
Here we prove that for W a finite Coxeter group and C a conjugacy class of W, there is always an element of C of maximal length in C which has excess zero. An element w \in W has excess zero if there exist elements $\sigma, \tau \in W$ such that $\sigma^2 = \tau^2 = 1, w = \sigma\tau$ and \ell(w) = \ell(\sigma) + \ell(\tau), with \ell being the length function on W.
