    • Quasicrystals, or more precisely "quasiperiodic crystals", are materials with perfect long-range order, but with no three-dimensional translational periodicity. The former is manifested in the occurrence of sharp diffraction spots and the latter in the presence of a noncrystallographic rotational symmetry. Icosahedral or dodecahedral units are presumed to be the building blocks of the quasicrystals.

    • It is emphasized that a Mackay icosahedron is not just an icosahedron but one enclosed in the dual M42 polyhedron as an outer shell.

    • Some quasicrystalline and cubic approximant phases have been observed from the rapidly solidified melts in the Mn-Al-Ge system. Their structures are not known except that they all appear to have icosahedral building units from their electron diffraction patterns. See, for example, (a) Lalla, N. P.; Tiwari, R. S.; Srivastava, O. N. J. Mater. Res. 1992, 7, 53.
