|---|---|---|---|---|---|---|
| O4 | O | 2a | 2 | 0.0000 | 0.0000 | 0.0000 |
| Fe2 | Fe | 8c | 8 | 0.2500 | 0.2500 | 0.2500 |

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 46 atoms drawn above are these sites multiplied by all 96 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
A6B16C_cI46_229_e_ch_a-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol cI46, then the space-group number 229, then the Wyckoff letters occupied by each element in turn (O: 2a; Fe: 8c; Dy: 12e; Fe: 24h). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
