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 48 atoms drawn above are these sites multiplied by all 6 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
A5BCD_hP48_169_5a_a_a_a-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol hP48, then the space-group number 169, then the Wyckoff letters occupied by each element in turn (Cl: 6a; Cl: 6a; Cl: 6a; Cl: 6a; Cl: 6a; Ga: 6a; O: 6a; Se: 6a). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
