The 14-faced Archimedean solid with faces 
. It is also the uniform
polyhedron with Maeder index 9 (Maeder 1997), Wenninger index 8 (Wenninger 1989),
Coxeter index 21 (Coxeter et al. 1954), and Har'El index 14 (Har'El 1993).
It has Schläfli symbol t
and Wythoff symbol 
. It is illustrated above together
with a wireframe version and a net that can be used for its
construction.
It is implemented in the Wolfram Language as PolyhedronData["TruncatedCube"] or UniformPolyhedron["TruncatedCube"]. Precomputed properties are available as PolyhedronData["TruncatedCube", prop].
The truncated cube is the convex hull of the great cubicuboctahedron, great rhombihexahedron, and quasirhombicuboctahedron uniform polyhedra.
The dual polyhedron of the truncated cube is the small triakis octahedron, both of which
are illustrated above together with their common midsphere.
