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 260 atoms drawn above are these sites multiplied by all 48 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
A12B14C35D4_cF260_196_abeg_2ef_cef2h_e-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol cF260, then the space-group number 196, then the Wyckoff letters occupied by each element in turn (Al: 4a; Al: 4b; O: 4c; Al: 16e; Ca: 16e; Ca: 16e; O: 16e; Zn: 16e; Ca: 24f; O: 24f; Al: 24g; O: 48h; O: 48h). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
