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 88 atoms drawn above are these sites multiplied by all 24 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

A7BC3_cP88_201_e2h_e_h-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol cP88, then the space-group number 201, then the Wyckoff letters occupied by each element in turn (Cl: 8e; Cu: 8e; Cl: 24h; Cl: 24h; Mo: 24h). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
