TL;DR: In this article, two-and three-dimensional quasicrystals were classified by their symmetry under rotation and showed that many disallowed crystal symmetries are allowed quasici-rystal symmets.
Abstract: A quasicrystal is the natural extension of the notion of a crystal to structures with quasiperiodic, rather than periodic, translational order. We classify two- and three-dimensional quasicrystals by their symmetry under rotation and show that many disallowed crystal symmetries are allowed quasicrystal symmetries. We analytically compute the diffraction pattern of an ideal quasicrystal and show that the recently observed electron diffraction pattern of an Al-Mn alloy is closely related to that of an icosahedral quasicrystal.
