Quasicrystal is a form of matter with an unusual arrangement of atoms. Although it’s called a “crystal” but it lacks symmetry. Unlike crystals, pattern within the quasicrystal does not repeat itself. They were first discovered in 1980s and since then the possible atomic arrangements violated the rules that fall under the category of crystals, that is, the materials could have only two-, three-, four- or six-fold symmetry.
