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 392 atoms drawn above are these sites multiplied by all 96 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
A2B5_cF392_216_4efg_4ef4h-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol cF392, then the space-group number 216, then the Wyckoff letters occupied by each element in turn (Pt: 16e; Pt: 16e; Pt: 16e; Pt: 16e; Zn: 16e; Zn: 16e; Zn: 16e; Zn: 16e; Pt: 24f; Zn: 24f; Pt: 24g; Zn: 48h; Zn: 48h; Zn: 48h; Zn: 48h). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
