Periodicity, Crystalline Lattices, Symbols, and Notationsute crystalline matter, the motif, are repeated in an orderly manner in the three-dimensional space. When a motif is systematically repeated, the result is a periodic pattern. The concepts of fundamental translation and crystalline lattice are introduced, a concept that allows the study of the cryst
