Polyhedron Model by Martin Berman, Biaugmented Truncated Cube

Berman, Martin · 1970

Two opposite faces of a truncated cube each have on them four equilateral triangles and five squares. The faces of the model are thus four regular octagons, ten squares, and sixteen equilateral triangles. On Berman's models of regular-faced convex polyhedra, see 1978.1065.01.
