Relations between the symbols of faces and edges in crystals of the hypohexagonal type

Abstract
As is known from the elementary course in crystallography, to determine the symbol [r₀, r₁, r₂, r₃] of the zone axis of a hexagonally isotropic complex from the symbols of two non-parallel faces (p₀, p₁, p₂, p₃) and (q₀, q₁, q₂, q₃) belonging to this zone, one can use the following method (see the article).
