This program gives access to the generators and general positions of subperiodic
groups, which contain the frieze, rod and layer groups.
Once the subperiodic group is chosen the number of the group as given in the
International Tables for Crystallography, Vol. E has to be specified.
You can give this number, if you know it, or you can choose it from the table with
the chossen group numbers and symbols if you click on the button
The available crystallographic data refer either to the standard/default setting of
the chose subperiodic group or to the so-called ITE Settings.
To get the data in a non conventional setting it is necessary to specify the
corresponding transformation that relates the non-conventional to the standard/default
setting of the chosen subperiodic group.
