The First Table of Atomic Site Coordinates of the Ih Quasicrystal

1. Introduction The mathematical derivation and classification of the 230 space groups were completed and perfected independently by Fedorov, Schoenflies, and Barlow before the twentieth century [1]. It was only later, in 1912, that Laue’s discovery of X-ray diffraction initiated...
