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 8 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

A4BC3_mC32_12_2j_i_ghi-002: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol mC32, then the space-group number 12, then the Wyckoff letters occupied by each element in turn (Sc: 4g; Sc: 4h; Rh: 4i; Sc: 4i; C: 8j; C: 8j). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
