Abstract

We study tetravalent analogues to fullerene systems which include Goldberg polyhedra (genus 0) and toroidal polyhedra (genus 1), where each node is connected to four others. According to the Euler-Poincaré formula, a tetravalent polyhedron with genus 0 has exactly 8 triangles, while on a toroidal polyhedron, the number of triangles and pentagons must be equal. We develop a construction method for toroidal polyhedra using a methodology similar to our previous work, which categorizes tetravalent toroidal polyhedra with a set of five indices. Bead models of the tori are presented as well.
