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 56 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

A3B2CD8_cP56_212_d_c_a_ce-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol cP56, then the space-group number 212, then the Wyckoff letters occupied by each element in turn (Ni: 4a; Li: 8c; O: 8c; Ge: 12d; O: 24e). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
