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 16 atoms drawn above are these sites multiplied by all 48 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

AB4C3_cP16_223_a_e_c-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol cP16, then the space-group number 223, then the Wyckoff letters occupied by each element in turn (Na: 2a; Pt: 6c; O: 8e). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
