Lattice Type
| 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.

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 |
