Symbol of a plane passing through three atoms

Abstract

According to the essence of the basic law of crystal chemistry, the position of each individual atom is expressed in coordinates (see article), where both numerators and denominators are integers, and, moreover, the denominators are certainly numbers greater than the numerators if the points are located inside an elementary parallelohedron or on its surface. Using the results, we can easily directly obtain the symbol of the edge passing through them using the symbols of three points.
