[Pw_forum] symmetry operations

[Marcello Rosini]

Hallo everybody,
I noticed this apparent inconsistency with pw.x: when I start a relax 
calculation the output says
6 symmetry operations and point group C_3v
when restarting the same calculation, the output says
2 symmetry operations and point group C_s
How can it be possible?
Thanks for help
Marcello
