Elementary derivation of the formula for determining the density of faces and edges of a hypohexagonal-isotropic complex

Abstract

Even from the preceding note, one can see the importance, in the initial study of crystallography, of deriving special elementary formulas for determining the density of isotropic complexes, both cubic and hypohexagonal. Beginners become acquainted with the technique of determining densities from tables best and most easily precisely on examples of isotropic complexes, since the simple formulas provide an ideal check on the determinations made and immediately acquaint them practically with the degree of accuracy—or rather inaccuracy—of graphical operations.
