Hexahedral Graph


HexahedralGraphs

A hexahedral graph is a polyhedral graph on six vertices. There are seven distinct hexahedral graphs (illustrated above) which, through duality, correspond to seven convex hexahedra. The hexahedral graphs were first enumerated by Steiner (1828; Duijvestijn and Federico 1981).

Three of the hexahedral graphs correspond to the skeletons of the pentagonal pyramid (i.e., the wheel graph W_6), triangular prism, and octahedron (square dipyramid, triangular antiprism). An additional hexahedron can be obtained by truncation of two of the four apexes of the tetrahedron, producing a solid composed of 2 triangles, 2 quadrilaterals, and two pentagons which, like the cube, has 6 faces, 8 vertices, 12 edges and cubic connectivity.
