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 176 atoms drawn above are these sites multiplied by all 192 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

A10B_cF176_227_cfg_d-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol cF176, then the space-group number 227, then the Wyckoff letters occupied by each element in turn (Al: 16c; V: 16d; Al: 48f; Al: 96g). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
