Macro and microsymmetryin relation with compound properties are discussed in detail. Both Schoenfliess and Hermann-Maugin notations are explained. Various approaches to generation of equivalent and special positions are trained. Real structures, crystal morphology, applications in crystallography and IR/Raman spectroscopy are discussed.
