+      The symmetry code of each atom site as the symmetry operation
+      number 'n' and the higher-dimensional translation 'm1...mp'.
+      These numbers are combined to form the code 'n m1...mp' or
+      n_m1...mp. The character string n_m1...mp is composed as follows:
+      'n' refers to the symmetry operation that is applied to the
+      superspace coordinates. It must match a number given in
+      _space_group_symop.ssg_id. 'm1...mp' refer to the translations
+      that are subsequently applied to the symmetry-transformed
+      coordinates to generate the atom used in calculating the angle.
+      These translations (t1,...tp) are related to (m1...mp) by the
+      relations m1=5+t1, ..., mp=5+tp. By adding 5 to the translations,
+      the use of negative numbers is avoided. The number 'p' must agree
+      with (_cell.modulation_dimension + 3). If there are no cell
+      translations, the translation number may be omitted. If no
+      symmetry operations or translations are applicable, then a single
+      full stop '.' is used.
