Several simplified techniques for graphically solving crystallography problems

Abstract

This note contains neither any significant innovations nor any systematic solution to graphical issues. But with the widespread development of graphic solutions that crystallography has received recently, and especially with the introduction of crystal chemical analysis, the most insignificant simplification or reduction in techniques acquires very significant practical significance. Finally, some rules that lead to a reduction in graphic operations in a particular specialty, their applications only in certain, although numerous, cases, are inconvenient to place in elementary courses, where only the rules of the most general significance should be considered, and, moreover, presented systematically, so that students receive a valid ability to solve problems of all kinds, even if not always in the simplest way.
