Small Rhombicuboctahedron
An Archimedean Solid also (inappropriately) called the Truncated Icosidodecahedron. This name is inappropriatesince truncation would yield rectangular instead of square faces. Its Dual Polyhedron is the DeltoidalIcositetrahedron, also called the Trapezoidal Icositetrahedron. It has Schläfli Symbolr
. It is also Uniform Polyhedron 
and has Wythoff Symbol 
. ItsInradius, Midradius, and Circumradius for

A version in which the top and bottom halves are rotated with respect to each other is known as the ElongatedSquare Gyrobicupola.See also Elongated Square Gyrobicupola, Great Rhombicuboctahedron (Archimedean), Great Rhombicuboctahedron (Uniform)
