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

AB2C8D_oP24_49_e_q_2qr_f-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol oP24, then the space-group number 49, then the Wyckoff letters occupied by each element in turn (Cs: 2e; Pr: 2f; Mo: 4q; O: 4q; O: 4q; O: 8r). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
