| Abstract: | In this paper we generalise Singerman’s results on triangle group inclusions to the broader class of generalised quadrangle groups, that is, Fuchsian groups with signature of genus 0 and generated by three or four elliptic generators. For any possible inclusion P<Q P<Q we also give the number of non-conjugate subgroups of Q isomorphic to P. |
