Constructions of Chiral Polytopes of Small Rank
Antonio Breda D'Azevedo, Gareth A. Jones, Egon Schulte
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…
Strong double coverings of groups
Ana Breda, Antonio Breda d'Azevedo, Domenico Catalano
By a covering of a group G we mean an epimorphism from a group F to G. Introducing the notion of strong covering as a covering pi:F-->G such that every automorphism of G is a proje…
Bipartite-uniform hypermaps on the sphere
Antonio Breda d'Azevedo, Rui Duarte
A hypermap is (hypervertex-) bipartite if its hypervertices can be 2-coloured in such a way that ``neighbouring'' hypervertices have different colours. It is bipartite-uniform if w…
