The generalized Petersen graph "G"("n","k") is formed by connecting the vertices of a regular "n"-gon to the corresponding vertices of a star polygon with Schläfli symbol {"n"/"k"}. For instance, in this notation, the Petersen graph is "G"(5,2): it can be formed by connecting corresponding vertices of a pentagon and five-point star, and the edges in the star connect every second vertex. The generalized Petersen graphs also include the "n"-prism "G"("n",1) the Dürer graph "G"(6,2), the Möbius-Kantor graph "G"(8,3), the dodecahedron "G"(10,2), the Desargues graph "G"(10,3) and the Nauru graph "G"(12,5).
