Abstract
Gareth Jones asked during the 2014 SIGMAP conference for examples of regular dessins with nonabelian fields of moduli. In this paper, we first construct dessins whose moduli fields are nonabelian Galois extensions of the form , where is an odd prime and is a th root of unity and is not a th power, and we then show that their regular closures have the same moduli fields. Finally, in the special case we give another example of a regular dessin with moduli field of degree and genus .
