A simple graphical method for identifying crystal face symbols on a stereographic projection

Abstract

It is no coincidence that the author did not title this article as a new method for determining symbols. Being a combination of two already known methods, this method cannot be called new. It turns out that two methods - the method of Prof. O. M. Anshelis and a slightly modified method of belts with their joint application make the process of determining symbols simpler than when using each of these methods separately.However, the purpose of this article is not only to show a method for such a joint application of these methods, but also to give a simple and independent conclusion and proof of the proposed combined method. The author considers it necessary to give such an independent conclusion in order to make this method quite accessible, both practically and theoretically, even to persons unfamiliar with the methods on which the proposed method is based, from which the proposed method originated.
