Figure 1451 shows the 2-D (two-dimensional) quasiperiodic octagonal tiling with diffraction symmetry 8mm. The two highlighted partitions in Figure 1451 (b) clearly show the differences between them.
Examples of octagonal quasicrystal structures are V-Ni-Si, Cr-Ni-Si, Mn-Si, Mn-Si-Al and Mn-Fe-Si alloys.
