Symmetry dictionary (symCIF) version 1.0.1

_space_group.name_H-M_ref

Name:
'_space_group.name_H-M_ref'

Definition:

   The short international Hermann-Mauguin space-group symbol as
   defined in Section 2.2.3 and given as the first item of each
   space-group table in Part 7 of International Tables
   for Crystallography Volume A (2002).

   Each component of the space-group name is separated by a
   space or an underscore character. The use of a space is
   strongly recommended.  The underscore is only retained
   because it was used in old CIFs. It should
   not be used in new CIFs.

   Subscripts should appear without special symbols. Bars
   should be given as negative signs before the numbers to which
   they apply.  The short international Hermann-Mauguin symbol
   determines the space-group type uniquely. However, the
   space-group type is better described using
   _space_group.IT_number or _space_group.name_Schoenflies. The
   short international Hermann-Mauguin symbol contains no
   information on the choice of basis or origin. To define the
   setting uniquely use _space_group.name_Hall, list the symmetry
   operations or generators, or give the transformation that
   relates the setting to the reference setting defined in this
   dictionary under _space_group.reference_setting.

   _space_group.name_H-M_alt may be used to give the
   Hermann-Mauguin symbol corresponding to the setting used.

   In the enumeration list, each possible value is identified by
   space-group number and Schoenflies symbol.
