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 24 atoms drawn above are these sites multiplied by all 8 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
A3B2CD6_mC24_12_ag_h_c_ij-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol mC24, then the space-group number 12, then the Wyckoff letters occupied by each element in turn (Ag: 2a; Li: 2c; Ag: 4g; Ir: 4h; O: 4i; O: 8j). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
