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 36 atoms drawn above are these sites multiplied by all 48 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

AB11_cP36_221_c_agij-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol cP36, then the space-group number 221, then the Wyckoff letters occupied by each element in turn (Hg: 1a; Ba: 3c; Hg: 8g; Hg: 12i; Hg: 12j). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
