SymPol is a C++ tool to work with symmetric polyhedra. It helps to compute restricted automorphisms (parts of the linear symmetry group) of polyhedra and performs polyhedral description conversion up to a given or computed symmetry group. You may download the complete SymPol package (version 0.1.8) and then follow the instructions below. Additional background information can be found in [BDS09] and in the Diploma thesis of the author Thomas Rehn.
