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 160 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
A13B6C_cF160_226_bi_f_a-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol cF160, then the space-group number 226, then the Wyckoff letters occupied by each element in turn (Os: 8a; Ag: 8b; O: 48f; Ag: 96i). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
