Dear QE users and developers,<br> I run two calculations of two crystal structures with D6h symmetry, but they gave different number of symmetry operations. Two crystal structures are unit cell (1*1*1) structure and a 4*4*4 supercell expanded by unit cell. The unit cell and supercell give 24 and 12 symmetry operations, respectively. Does anyone know why? Thanks a lot.<br>
