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 360 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

A4BC4D6_cP360_222_2i_h_2i_3i-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol cP360, then the space-group number 222, then the Wyckoff letters occupied by each element in turn (Co: 24h; C: 48i; C: 48i; H: 48i; H: 48i; O: 48i; O: 48i; O: 48i). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
