Dear PWscf authors and users,

My calculation was failed immediatly after start with the next error message:

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
     task #         2
     from coset : error #         0
     The order of the group is not a multiple of that of the subgroup
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

What does it mean? I looked at my input file and did not see any strange things. What causes this error?

 Thanks in advance,
   Sergey
