Quartz file data loaded with
exact application of symmetry operators (load
quartz.cif {555 555 0}). Only four of the nine atoms
are contained within cell 555. In this case, there are six symmetry
operators, including the identity operation. Note that the Si atoms
(large) are in special positions and are generated by two symmetry
operators each, while the O atoms (small) are in general
positions. |
