## Program Torsionfree

### Usage

Torsionfree 'file' [-t]

file: bravais_TYP containg generators for a space group
### Description

Decides whether the given space group is a torsion
free space group.

If so, it additionally decides whether it has trivial center.
### Options

-t : Output for TeX. Do not use!

### Remarks

CAUTION: The program assumes that the translation lattice is in fact Z^{n}. This is not
checked.

See also for Order.

### Examples

- Find the fundamental group of the Handtsche-Wendt
manifold!
- Find all Z-classes, affine classes and torsion free space
groups in a given Q-class.
