In Conway polyhedron notation it can be seen as gT, a gyro tetrahedron. : Rhombic dodecahedron Rhombic dodecahedron The rhombic dodecahedron is a zonohedron with twelve rhombic faces and octahedral symmetry. Source: Internet

It is also unique among the Platonic solids in having faces with an even number of sides and, consequently, it is the only member of that group that is a zonohedron (every face has point symmetry). Source: Internet
