The **antirhombicosicosahedron**, **arie**, or **compound of five cuboctahedra** is a uniform polyhedron compound. It consists of 40 triangles (which form coplanar pairs combining into 20 hexagrams) and 30 squares, with two of each joining at a vertex.

It can be thought of as a rectification of either the small icosicosahedron or the rhombihedron, or the cantellation of the chiricosahedron. Each individual component has pyritohedral symmetry.

Its quotient prismatic equivalent is the cuboctahedral pentagyroprism, which is seven-dimensional.
