## Program KSubgroups

### Usage

    KSubgroups 'file1' [-h] [-a [-n]] [-f] [-t] [-p 'file2'] 'p_1' ... 'p_n'

file1: Spacegroup R in standard affine form (without translations)
file2: (optional) Pointgroup G of R (with correct normalizer)
pi : primes

### Description

Calculates the maximal klassengleich subgroups of R with pi-power index.

### Options

    -h   : Give a short help.
    -a   : Calculate subgroups up to conjugation under
           the affine normalizer of R.
    -n   : Print the lengthes of the orbits
           (this only works together with the option a).
    -f   : Print the subgroups in files 'file1_j'.
    -t   : Omit the last dim R generators.
    -d   : Only for debugging!

### Remarks

See also for Graph, KSupergroups and Standard_affine_form.

### Examples

1. Calculate minimal/maximal klassengleich/translationengleich super-/sub-groups of a given space group up to conjugation under the affine normalizer of this group.
