Rectified icosiheptaheptacontadipeton

The rectified icosiheptaheptaheptacontadipeton, or rojak, also called the rectified 221 polytope, is a convex uniform polypeton. It consists of 27 demipenteracts, 27 rectified triacontaditera, and 72 rectified hexatera. Two demipenteracts, 5 rectified triacontaditera, and 5 rectified hexatera join at each rectified pentachoric prismatic vertex. As the name suggests, it is the rectification of the icosiheptaheptacontadipeton.

The rectified icosiheptaheptacontadipeton contains the vertices of a small prismated hexateral prism and a triangular-triangular-hexagonal trioprism.
