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 32 atoms drawn above are these sites multiplied by all 4 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

AB3_mP32_14_2e_6e-002: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol mP32, then the space-group number 14, then the Wyckoff letters occupied by each element in turn (Cr: 4e; Cr: 4e; Te: 4e; Te: 4e; Te: 4e; Te: 4e; Te: 4e; Te: 4e). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
