in geometry, the stellated truncated hexahedron (or quasitruncated hexahedron, and stellatruncated cube) is a uniform star polyhedron, indexed as u. it is represented by schläfli symbol t'{4,3} or t{4/3,3}, and coxeter-dynkin diagram, . it is sometimes called quasitruncated hexahedron because it is related to the truncated cube, , except that the square faces become inverted into {8/3} octagrams.
