The concave equilateral dodecahedron, called an endo-dodecahedron. [clarification needed] A cube can be divided into a pyritohedron by bisecting all the edges, and faces in alternate directions. A regular dodecahedron is an intermediate case with equal edge lengths. A rhombic dodecahedron is a degenerate case with the 6 crossedges reduced to ...
For example, {3} is an equilateral triangle, {4} is a square, {5} a convex regular pentagon, etc. Regular star polygons are not convex, and their Schläfli symbols {p / q} contain irreducible fractions p / q, where p is the number of vertices, and q is their turning number. Equivalently, {p / q} is created from the vertices of {p}, connected ...

It has extended Schläfli symbol b{5, 5 ⁄ 2}, as a blended great dodecahedron, and Coxeter diagram. It has 4 Schwarz triangle equivalent constructions, for example Wythoff symbol 3 | 5 ⁄ 3 5, and Coxeter diagram.
For example, a chamfered cube, cC, can be constructed as t 4 daC, as a rhombic dodecahedron, daC or jC, with its degree-4 vertices truncated. A lofted cube, lC is the same as t 4 kC. A quinto-dodecahedron, qD can be constructed as t 5 daaD or t 5 deD or t 5 oD, a deltoidal hexecontahedron, deD or oD, with its degree-5 vertices truncated.
The rhombicosidodecahedron shares its vertex arrangement with three nonconvex uniform polyhedra: the small stellated truncated dodecahedron, the small dodecicosidodecahedron (having the triangular and pentagonal faces in common), and the small rhombidodecahedron (having the square faces in common).
