Figure 4.6.3.15
Atomic surface of the Penrose tiling in the 5D hypercubic description. The projection of the 5D hypercubic unit cell upon gives a rhombicosahedron (above). The Penrose tiling is generated by four equidistant pentagons (shaded) inscribed in the rhombicosahedron. Below is a perpendicularspace projection of the same pentagons, which are located on the diagonal of the 4D hyperrhombohedral unit cell in the 4D description.
