Space groups are assigned to crystal systems according to their point groups.

The distribution of the 32 point groups into the 7 crystal systems is given in the following table.

For the correspondence of the two systems below, see crystal system.

They are among the crystallographic point groups of the cubic crystal system.

All members of the series belong to the monoclinic crystal system with point group 2/m.

A crystal system is a class of point groups.

Each of these crystal systems is represented by a primitive lattice.

These twin laws are specific to the crystal system.

They are similar to but not quite the same as the seven crystal systems and the six crystal families.

Each one can be classified into one of the seven crystal systems.
