Truncated rhombicuboctahedron


The truncated rhombicuboctahedron is a polyhedron, constructed as a truncated rhombicuboctahedron. It has 50 faces, 18 octagons, 8 hexagons, and 24 squares.
It can fill space with the truncated cube, truncated tetrahedron and triangular prism as a truncated runcic cubic honeycomb.

Other names

As a zonohedron, it can be constructed with all but 12 octagons as regular polygons. It has two sets of 48 vertices existing on two distances from its center.
It represents the Minkowski sum of a cube, a truncated octahedron, and a rhombic dodecahedron.

Excavated truncated rhombicuboctahedron

The excavated truncated rhombicuboctahedron is a toroidal polyhedron, constructed from a truncated rhombicuboctahedron with its 12 irregular octagonal faces removed. It comprises a network of 6 square cupolae, 8 triangular cupolae, and 24 triangular prisms. It has 148 faces, 312 edges, and 144 vertices. With Euler characteristic χ = f + v - e = -20, its genus is 11.
Without the triangular prisms, the toroidal polyhedron becomes a truncated cuboctahedron.

Related polyhedra

The truncated cuboctahedron is similar, with all regular faces, and 4.6.8 vertex figure.
The triangle and squares of the rhombicuboctahedron can be independently rectified or truncated, creating four permutations of polyhedra. The partially truncated forms can be seen as edge contractions of the truncated form.
The truncated rhombicuboctahedron can be seen in sequence of rectification and truncation operations from the cuboctahedron. A further alternation step leads to the snub rhombicuboctahedron.
