Dear QE users,
Thank you for your help.
I built a monolayer CrI3 structure. However, in the scf calculation, it only
find 2 symmetry operation. For monolayer CrI3, it should belong to D3d point
group and have 12 symmetry operactions.
Here I attached my input file. Please help me check. Thank you very much for
your help.
