Definition:
A code which identifies a cluster of atoms that show long-range positional disorder but are locally ordered. Within each such cluster of atoms, _atom_site_disorder_group is used to identify the sites that are simultaneously occupied. This field is only needed if there is more than one cluster of disordered atoms showing independent local order.Examples:
| A | disordered methyl assembly with groups 1 and 2 |
| B | disordered sites related by a mirror |
| S | disordered sites independent of symmetry |
