List of uniform polyhedra by vertex figure — There are many relations among the uniform polyhedron.Some are obtained by truncating the vertices of the regular or quasi regular polyhedron.Others share the same vertices and edges as other polyhedron.The grouping below exhibit some of these… … Wikipedia
Isohedral figure — In geometry, a polytope (a polyhedron or a polychoron for example) or tiling is isohedral or face transitive when all its faces are the same. More specifically, all faces must be not merely congruent but must be transitive , i.e. must lie within… … Wikipedia
Isogonal figure — In geometry, a polytope (a polygon, polyhedron or tiling, for example) is isogonal or vertex transitive if all its vertices are the same. That is, each vertex is surrounded by the same kinds of face in the same order, and with the same angles… … Wikipedia
