Cubitruncated Cuboctahedron

The Uniform Polyhedron $U_{16}$ whose Dual is the Tetradyakis Hexahedron. It has Wythoff Symbol $3\,{\textstyle{4\over 3}}\,4\,\vert$. Its faces are $8\{6\}+6\{8\}+6\{{\textstyle{8\over 3}}\}$. It is a Faceted Octahedron. The Circumradius for a cubitruncated cuboctahedron of unit edge length is

$$R={\textstyle{1\over 2}}\sqrt{7}\,.$$
