|---|---|---|---|---|---|---|
| Pa3 | Pa | 4c | 4 | 0.0000 | 0.0000 | 0.0000 |
| Rb4 | Rb | 4g | 4 | 0.0000 | 0.2500 | 0.4532 |
| F1 | F | 8n | 8 | 0.8206 | 0.2500 | 0.1459 |

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 32 atoms drawn above are these sites multiplied by all 16 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
A6BC_oC32_67_no_c_g-001: the stoichiometry comes first (A, B, C… are the elements in alphabetical order of their site labels), then the Pearson symbol oC32, then the space-group number 67, then the Wyckoff letters occupied by each element in turn (Pa: 4c; Rb: 4g; F: 8n; F: 16o). Two structures with the same label are the same arrangement with different cell parameters or coordinates.
