Regular dessins uniquely determined by a nilpotent automorphism group
Naer Wang, Roman Nedela, Kan Hu
It is well known that the automorphism group of a regular dessin is a two-generator finite group, and the isomorphism classes of regular dessins with automorphism groups isomorphic…

Nilpotent groups of class two which underly a unique regular dessin
Kan Hu, Roman Nedela, Naer Wang
A dessin is an embedding of connected bipartite graph into an oriented closed surface. A dessin is regular if its group of colour- and orientation-preserving automorphisms acts tra…
