Supergroups of a Given Type

Different supergroups ...
The program SUPERGROUPS will give you all of the different supergroups of the same type with specified index for a given group-supergroup pair.

As an input data you should give (or select) the numbers of the group and the supergroup, and the index.

The procedure for the calculation of all of the supergroups is based on the normalizers of the space groups. By default the Euclidean normalizers are used. If you want to use other normalizer, please select it from the list.
