Program Reverse_name
Usage
Reverse_name [-c] [-i]
Description
The program enables you to construct a space group corresponding
to a name as given by CARAT. The program will read the various
components of the name for the desired space group from stdin.
It will then output generators for the space group, which are
understood to generate the space group together with Zn.
Please note: not every name is a valid name!
Options
-c : do not check the name given, ie. verify that it is a valid name.
WARNING: this could lead to a wrong name in the header of the
resulting group
-i : ignore that the name is invalid, and give a space group at least
in the desired Q-class, and if exists one in the desired Z-class.
If given without -c the resulting group will also indicate the valid
name.
Remarks
Note:
| The Q-classes in | correspond to the Q-classes in degree |

| min.1, max.1 | 1 |
| min.2-5, group.1-4, max.2-3 | 2 |
| min.6-14, group.5-25, max.4-5 | 3 |
| min.15-57, group.26-205, max.6-9 | 4 |
| min.58-169, group.206-1042, max.10-15 | 5 |
| min.170-667, group.1043-7636, max.16-27 | 6 |
