The multiplicity and the Wyckoff letter say how many copies of the site the group makes in one cell and on which kind of symmetry element the site sits; the 96 atoms drawn above are these sites multiplied by all 192 operations. Press Wyckoff under Colour to see the sites, and tick a symmetry element on the left to see which atoms lie on it.

How to read the label

A2B_cF96_227_abf_cd-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol cF96, then the space-group number 227, then the Wyckoff letters occupied by each element in turn (O: 8a; O: 8b; Sb: 16c; Sb: 16d; O: 48f). Two structures with the same label are the same arrangement with different cell parameters or coordinates.

Note: D6₂ (Obsolete).
