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 132 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

A4B5C22D2_oC132_20_abc_a2c_2a10c_c-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol oC132, then the space-group number 20, then the Wyckoff letters occupied by each element in turn (Cs: 4a; Mo: 4a; O: 4a; O: 4a; Cs: 4b; Cs: 8c; Mo: 8c; Mo: 8c; O: 8c; O: 8c; O: 8c; O: 8c; O: 8c; O: 8c; O: 8c; O: 8c; O: 8c; O: 8c; P: 8c). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
