Name:
'_space_group.IT_number'

Definition:

   The number as assigned in International Tables for
   Crystallography Volume A, specifying the proper affine
   class (i.e. the orientation-preserving affine class) of
   space groups (crystallographic space-group type) to which
   the space group belongs.  This number defines the space-group
   type but not the coordinate system in which it is expressed.
