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 488 atoms drawn above are these sites multiplied by all 96 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

A12B36CD12_cF488_210_h_3h_a_fg-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol cF488, then the space-group number 210, then the Wyckoff letters occupied by each element in turn (Mg: 8a; O: 48f; O: 48g; B: 96h; H: 96h; H: 96h; H: 96h). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
