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 160 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

A17B3_cI160_204_def2gh_g-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol cI160, then the space-group number 204, then the Wyckoff letters occupied by each element in turn (Be: 12d; Be: 12e; Be: 16f; Be: 24g; Be: 24g; Ru: 24g; Be: 48h). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
