The stericantitruncated 5-cube, also called the celligreatorhombated penteract or cogrin, is a convex uniform 5-polytope. It consists of 80 cuboctahedral prisms, 80 triangular-octagonal duoprisms, 40 great rhombicuboctahedral prisms, 10 great rhombated tesseracts, and 32 prismatorhombated pentachora. 1 prismatorhombated pentachoron, 1 cuboctahedral prism, 1 great rhombated tesseract, 1 triangular-octagonal duoprism, and 2 great rhombicuboctahedral prisms join at each vertex. As the name suggests, it is the stericantitruncation of the 5-cube.
