quasitruncated hexahedron

The uniform polyhedron U_19, also called the quasitruncated hexahedron, whose dual polyhedron is the great triakis octahedron. It has Schläfli symbol t'{4, 3}, Wythoff symbol 23|4/3, and is Wenninger model W_92. Its faces are 8{3} + 6{8/3}. For a = 1, its circumradius is R = 1/2 sqrt(7 - 4sqrt(2)). The convex hull of the stellated truncated hexahedron is the Archimedean small rhombicuboctahedron A_6, whose dual is the deltoidal icositetrahedron, so the dual of the stellated truncated hexahedron (i.e., the great triakis octahedron) is one of the stellations of the deltoidal icositetrahedron.
