In order to determine the Weierstrass points of a compact connected Riemann surface of genius at least 3 the knowledge of the permutation groups (G, \Omega) with fixity at most 4 is needed, i.e. a non-trivial element in G fixes at most 4 points in \Omega. I will discuss the classification of these groups by focusing on the case that (G, \Omega) is of fixity 4. This is a joint project with Kay Magaard and Rebecca Waldecker.
