The runcitruncated 5simplex, also called the prismatotruncated hexateron or pattix, is a convex uniform 5polytope. It consists of 15 octahedral prisms, 20 triangularhexagonal duoprisms, 6 small rhombated pentachora, and 6 prismatorhombated pentachora. One small rhombated pentachoron, 1 octahedral prism, 2 prismatorhombated pentachora, and 2 triangularhexagonal duoprisms join at each vertex. As the name suggests, it is the runcitruncation of the 5simplex.
