http://openmopac.net/manual/symmetry.html WebSYMMETRY does not involve any point-group symmetry or symmetry theory. When SYMMETRY is used, the symmetry relations between coordinates are defined by the user. These can be used for defining the point-group of a molecule, for example the D 6h of benzene, but no point-group theory is used when SYMMETRY is specified.
