Construction of edges using symbols in hypohexagonal crystals

Abstract

The article raises the question of constructing edges from symbols in crystals for hypohexonal-type complexes, which has not yet been raised by anyone. Of course, it is extremely simple and similar to the solution for the cubic type. I have shown that in hypohexagonal complexes, the symbols of the edges are such that, in the special case of a hypohexagonal-isotropic complex, the indices of the edges and perpendicular faces are the same, as required by the theory of synclines (because in this case, the ellipsoid of synclines is a sphere).
