**Description:**

Contains information about Wyckoff positions of a space group. Only one site can be given for each special position but the remainder can be generated by applying the symmetry operations stored in _space_group_symop.operation_xyz.

Example 1 - this example is taken from the space group F d -3 c (No. 228,
origin choice 2). For brevity only a selection of special positions
are listed. The coordinates of only one site per special position can
be given in this item, but the coordinates of the other sites can be
generated using the symmetry operations given in the SPACE_GROUP_SYMOP
category.
