The following table contains a list of point groups with representative molecules.

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.

In the classification of crystals, each point group is also known as a crystal class.

A crystal system is a class of point groups.

Her work included contributions to the theory of point groups.

Only 10 of the 32 point groups are polar.

In each case a 3-dimensional point group is formed.

The first step in this process is assigning a point group to the molecule.

Each operation in the point group is performed upon the molecule.
