Bi-orientable maps (also called pseudo-orientable maps) were introduced by Wilson in the seventies to describe non-orientable maps with the property that opposite orientations can consistently be assigned to adjacent vertices. In contrast to orientab

In this paper, we show that for any finite field [Formula: see text], any pair of map-generators (that is when one of the generators is an involution) of [Formula: see text] and [Formula: see text] has a group automorphism that inverts both generator

The n -dimensional abstract polytopes and hypertopes, particularly the regular ones, have gained great popularity over recent years. The main focus of research has been their symmetries and regularity. The planification of a polyhedron helps its spat

In the present paper we introduce a family of functors (called operations) of the category of hypermaps (dessins) preserving the underlying Riemann surface. The considered family of functors include as particular instances the operations considered b

Regular oriented hypermaps are triples ?$(G;a,b)$? consisting of a finite 2-generated group ?$G$? and a pair ?$a$?, ?$b$? of generators of ?$G$?, where the left cosets of ?$\langle a \rangle$?, ?$\langle b \rangle$? and ?$\langle ab \rangle$? describ

Bicontactual regular maps (regular maps with the property that each face meets only two others) were introduced and classified by Wilson in 1985. This property generalizes to hypermaps (cellular embeddings of hypergraphs in compact surfaces) giving r

An abstract polytope of rank n is said to be chiral if its automorphism group has precisely two orbits on the flags, such that adjacent flags belong to distinct orbits. The present paper describes a general method for deriving new finite chiral polyt
