General information
Spacegroup name

P 1 21 1
  Hermann-Mauguin space-group symbol. Note that the
  Hermann-Mauguin symbol does not necessarily contain complete
  information about the symmetry and the space-group origin. If
  used, always supply the FULL symbol from International Tables
  for Crystallography Vol. A (2002) and indicate the origin and
  the setting if it is not implicit. If there is any doubt that
  the equivalent positions can be uniquely deduced from this
  symbol, specify the _symmetry_equiv.pos_as_xyz or
  _symmetry.space_group_name_Hall data items as well. Leave
  spaces between symbols referring to
  different axes.
