This interactive application shows an initial face pole in stereographic projection and enables the comparison of results according to the action of each of the 5 symmetry classes (or point groups) of the cubic system after a click on one of the respective buttons on the right side of the figure. In each of the five classes can be noted four 3 fold axes or four 3 fold inversion axes, as required by the essential symmetry of the cubic crystal system.
A click on the stereographic diagram will change the position of the face pole.
Exercise
Locate in the corresponding diagram of stereographic projection the symmetry elements of each of the five classes of the cubic system.
