Dear QE users and developers,
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.
Feng
