This uniform polyhedron compound is a symmetric arrangement of 20 triangular prisms, aligned in pairs with the axes of three-fold rotational symmetry of an icosahedron. It results from composing the two enantiomorphs of the compound of 10 triangular prisms.
It shares its vertex arrangement with the rhombidodecadodecahedron.
