On Pentagonal Geometries with Block Size 3, 4 or 5,e also prove that there exists a PENT(4, .) for . 1 (mod 8) and a PENT(5, .) for . 1 (mod 5), ., apart from nine possible exceptions. Further we construct an infinite class of pentagonal geometries PENT(.), ., and a PENT(6, 13).

,The Grothendieck-Teichmüller Group of a Finite Group and ,-Dessins d’enfants, calculations. It turns out that the classical action of the Grothendieck-Teichmüller group on dessins d’enfants can be refined to an action on “.-dessins”, which we define, and this elucidates much of the first part.

Powers of Skew-Morphisms,mplementary products of finite groups . with . cyclic and .. As natural generalizations of group automorphisms, they share many of their properties but proved much harder to classify. Unlike automorphisms, not all powers of skew-morphisms are skew-morphisms again. We study and classify the powers of

Census of Quadrangle Groups Inclusions,e and quadrangle groups forming a particular subfamily of Fuchsian groups. With two exceptions, each inclusion determines a finite bipartite map (hypermap) on a 2-dimensional spherical orbifold that encodes the complete information and gives a graphical visualisation of the inclusion.
