Definition:
A parsable string giving one of the symmetry operations of the superspace group in algebraic form. These data will generally be repeated in a loop. Use symbols as necessary according to _cell_modulation_dimension. All symmetry operations should be entered, including the identity operation, those for lattice centring and that for a centre of symmetry, if present. The symbolic notation for coordinates is such that the identity operation is expressed as x1,x2,x3,...,xn. _space_group_symop_ssg_operation_algebraic must always be present in a CIF corresponding to a modulated structure.Example:
x1,-x2,x3,1/2+x4 |
Appears in list containing _space_group_symop_ssg_id
Type: char
Category: space_group_symop
