Abstract

The prism over a graph GG is the Cartesian product of GG with the complete graph on two vertices. A graph GG is prism-hamiltonian if the prism over GG is hamiltonian. We prove that every polyhedral graph (i.e. 3-connected planar graph) of minimum degree at least four is prism-hamiltonian.
