Series of Maximal Isomorphic Subgroups

Series of maximal isomorphic subgroups
For each space group you can obtain the list with its maximal isomorphic subgroups. The list contains the numbers and the symbols of the maximal subgroups as well as, the corresponding index and the transformation matrix that relates the basis of the group with that of the subgroup. It is worth to take account of:
  • the program uses the default choice for the group setting.
  • only maximal isomorphic subgroups with index less or equal to 27 are displayed (125, in the case of cubic groups)

If you are using this program in the preparation of a paper, please cite it in the following form:

Aroyo, et. al. Zeitschrift fuer Kristallographie (2006), 221, 1, 15-27.

Please, enter the sequential number of group as given in International Tables for Crystallography, Vol. A

NOTE: Other possibility is to define a maximum index for the parametric series of maximal isomorphic subgroups.
