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 28 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

A5B5C4_tP28_104_ac_ac_c-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol tP28, then the space-group number 104, then the Wyckoff letters occupied by each element in turn (Ba: 2a; Bi: 2a; Ba: 8c; Bi: 8c; In: 8c). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
