SUMMARY:Twisted honeycombs and abstract polytopes
DESCRIPTION:In the 70´s Coxeter considered the 4-dimensional regular polytopes and used
the so-called Petrie Polygons to obtain quotients of the polytopes that, while
having all possible rotational symmetry, lack reflectional symmetry. He called
these objects Twisted Honeycombs. Nowadays, objects with such symmetry
properties are often called chiral. In this talk I will review Coxeter´s
twisted honeycombs and explore a natural way to extend Coxeter´s work to
polytope-like structures, in particular, we shall see some properties and
examples of so-called chiral skeletal polyhedra, and an application of them.
