 If the basis is primitive, the unit cell is called the [[primitive cell]]. It contains only one lattice point. If the basis is non-primitive, the unit cell is a [[centred lattices|multiple cell]] and it contains more than one lattice point. The multiplicity of the cell is given by the ratio of its volume to the volume of a primitive cell.
