The **small rhombated hexadecachoron** is a convex semi-uniform polychoron that is a variant of the rectified icositetrachoron with tesseractic symmetry. As such it can be represented by o4y3o3x, and has 8 cuboctahedra of size y, 16 rhombitetratetrahedra of type x3o3y, and 24 square prisms of type x y4o as cells, with two edge lengths.
