Octahemioctahedron


U03

The octahemioctahedron, also called the octatetrahedron, is the uniform polyhedron with Maeder index 3 (Maeder 1997), Wenninger index 68 (Wenninger 1989), Coxeter index 37 (Coxeter et al. 1954), and Har'El index 8 (Har'El 1993). It has Wythoff symbol 3/23|3 and its faces are 8{3}+4{6}. It is a faceted cuboctahedron.

The octahemioctahedron is implemented in the Wolfram Language as UniformPolyhedron[68], UniformPolyhedron["SmallDitrigonalIcosidodecahedron"], UniformPolyhedron[{"Coxeter", 37}], UniformPolyhedron[{"Kaleido", 8}], UniformPolyhedron[{"Uniform", 3}], or UniformPolyhedron[{"Wenninger", 68}]. It is also implemented in the Wolfram Language as PolyhedronData["Octahemioctahedron"].

CuboctahedralGraph

Its skeleton is the cuboctahedral graph, illustrated above in a number of embeddings.

U03Hull

The convex hull of the octahemioctahedron is the cuboctahedron.

For unit edge lengths, its circumradius is

 R=1.

Its dual polyhedron is the octahemioctacron.
