Magma source code of the implementation
The source code of the implemented version of Voronoi's algorithm is available as a text file here.
Note that you need QHULL on your computer to use this algorithm. You need to specify the installation directory of QHULL on your computer in the allotted place in the source code.
The algorithm may be used by specifying the data (n,d and the fractional ideal) in the source code. Then simply use Magma's load-command.
The algorithm willl create a GAP-readable list of group numbers in order to identify the isomorphism type of the automorphism groups of the involved lattices.
