It should possess the same symmetry as the crystal structure. If there is a choice between more than one repeating arrangements, the one which has the smallest number of atoms (i.e., smallest volume) is chosen as th unit cell. Such a unit cell is often labelled as the primitive ( or simple) unit cell representation.
