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 64 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
A6B2CD6E_cP64_208_m_ad_b_m_c-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol cP64, then the space-group number 208, then the Wyckoff letters occupied by each element in turn (Cs: 2a; Fe: 4b; Zn: 4c; Cs: 6d; C: 24m; N: 24m). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
