In geometry, the stellated truncated hexahedron (or quasitruncated hexahedron, and stellatruncated cube[1]) is a uniform star polyhedron, indexed as U19. It has 14 faces (8 triangles and 6 octagrams), 36 edges, and 24 vertices.[2] It is represented by Schläfli symbol t'{4,3} or t{4/3,3}, and Coxeter-Dynkin diagram, CDel node 1.pngCDel 4.pngCDel rat.pngCDel d3.pngCDel node 1.pngCDel 3.pngCDel node.png. It is sometimes called quasitruncated hexahedron because it is related to the truncated cube, CDel node 1.pngCDel 4.pngCDel node 1.pngCDel 3.pngCDel node.png, except that the square faces become inverted into {8/3} octagrams.

3D model of a stellated truncated hexahedron

Even though the stellated truncated hexahedron is a stellation of the truncated hexahedron, its core is a regular octahedron.

It shares the vertex arrangement with three other uniform polyhedra: the convex rhombicuboctahedron, the small rhombihexahedron, and the small cubicuboctahedron.
