## Generators and General Positions of 3D Crystallographic Point Groups

This program permits the access to the generators and the general positions for
a given three-dimensional crystallographic point group.

**Input**

a) To get the __generatos and the general positions__, one has to select a point group from the table with the symbols of the 32 three-dimensional crystallographic point groups. The point group symbols are given following the Shoenflies and the Hermann-Mauguin symbols as given in the *International Tables for Crystallography*, Vol. A.

b) To get a table with the __geometrical interpretation__ of the 32 three-dimensional crystallographic point groups symmetry operations one has to click on the link at the bottom of the table.

**Output**

a) Once the point group is chosen a table is shown with the information about the general positions. To get the information about the generatos one has to click in the link.

b) A table with the symbols of the 32 two-dimensional crystallographic groups is shown and the geometrical interpretation of their symmetry operations in Seitz notation.
