This dialog lists all the systems that are compatible
with the current settings in the entries <b>System</b>,
<b>Lattice</b> and <b>Group</b>. When the settings are
impossible, no systems are shown. When the entries
are empty, all 6 systems are shown.
<p/>
For each possible system, GAMGI lists its usual lower-case
symbol, the common designation, the lattices available and
the range of space groups where it occurs.
<p/>
GAMGI uses the less common anorthic name to designate the
triclinic system (as the International Tables for Crystallography
do), to use a different letter (a) from the tetragonal system (t).
GAMGI groups Hexagonal, Trigonal, Rombohedral in a single
Hexagonal system (thus corresponding to the 6 crystallographic
families of the International Tables for Crystallography).
<p/>
Clicking on a listed option in the lattice dialog, has
exactly the same effect as writing it directly on the
<b>System</b> entry.
