Truncated cube

The truncated cube, the truncated hexahedron, or tic, is one of the 13 Archimedean solids. It consists of 8 triangles and 6 octagons. Each vertex joins one triangle and two octagons. As the name suggests, it can be obtained by truncation of the cube.

Vertex coordinates
A truncated cube of edge length 1 has vertex coordinates given by all permutations and sign changes of
 * (±(1+$\sqrt{7+4√2}$)/2, ±(1+$\sqrt{2}$)/2, ±1/2).

Related polyhedra
A truncated cube can be augmented by attaching a square cupola to one of its octagonal faces, forming the augmented truncated cube. If a second square cupola is attached to the opposite octagonal face, the result is the biaugmented truncated cube.
