Hypermaps and multiply quasiplatonic Riemann surfaces (1104.0713v1)
Published 4 Apr 2011 in math.CO and math.GR
Abstract: Generalising an example by Girondo and Wolfart, we use finite group theory to construct Riemann surfaces admitting two or more regular dessins (i.e. orientably regular hypermaps) with automorphism groups of the same order, and in many cases with isomorphic automorphism groups.
