Abstract

The ff-vector of a polytope consists of the numbers of its ii-dimensional faces. An open field of study is the characterization of all possible ff-vectors. It has been solved in three dimensions by Steinitz in the early 19th century. We state a related question, i.e. to characterize ff-vectors of three dimensional polytopes respecting a symmetry, given by a finite group of matrices. We give a full answer for all three dimensional polytopes that are symmetric with respect to a finite rotation or rotary reflection group. We solve these cases constructively by developing tools that generalize Steinitz's approach.
