Cell Lattice
This dialog lists all the lattices that are compatible with the current settings in the entries System, Lattice and Group. When the settings are impossible, no lattices are shown. When the entries are empty, all 5 lattices are shown.

For each possible lattice, GAMGI lists its usual upper-case symbol, the description, the systems where it occurs and the number of groups with this centering.

Clicking on a listed option in the lattice dialog, has exactly the same effect as writing it directly on the Lattice entry.
