Bilbao Crystallographic Server Retrieval Tools Help Generators/General positions of the three-dimensional crystallogrpahic point groups |

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

**Input****Output**

a) To get the

b) To get a table with the

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.
