The truncated 5-orthoplex, also called the truncated triacontaditeron or tot, is a convex uniform 5-polytope. It consists of 10 regular hexadecachora and 32 truncated pentachora. One hexadecachoron and 8 truncated pentachora join at each vertex. As the name suggests, it is the truncation of the 5-orthoplex.
