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 11 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

ABC3D6_cP11_200_a_b_c_f-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol cP11, then the space-group number 200, then the Wyckoff letters occupied by each element in turn (Cs: 1a; Hg: 1b; N: 3c; O: 6f). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
