There are totally three lattice types which are:
         i) Primitive (P) lattices. In this case, there is only one lattice point per unit cell.
         ii) Body-centered (I) lattices. In this case, there is a lattice point at the corners and one in the center of the cell.
         iii) A-, B-, C- or F-centered lattices. In this case, there is a lattice point at the corners and others at one (A, B, C) or all three (F) of the faces.

Table 3021. Lattice types.

Lattice types Description
P Primitive (simple unit cell): Lattice points on corners only
I Body centered (from the German "Innenzentriert"): Lattice points on corners as well as in the center of the unit cell body
F Face centered (from the German "Flächenzentriert"): Lattice points on corners as well as in the centers of all faces of the unit cell
A Base centered on A faces only: Lattice points on corners as well as centered on bc-faces
B Base centered on B faces only: Lattice points on corners as well as centered on ac-faces
C Base centered on C faces only: Lattice points on corners as well as centered on ab-faces
R Rhombohedral: Hexagonal class only
