dm-averaging

Dear all,
once again a question concerning a slightly complicated case of dm and
ncs-averaging.
The situation:
Within the the asymmetric unit of my crystal there are six copies of the
protomer grouped as three dimers A, B and C.
I could determine the following symmetry operators:
inter-dimer: A -> B
B -> C
intra-dimer: A1 -> A2 (from subunit 1 of dimer A to subunit 2 of dimer
1)
B1 -> B2
C1 -> C2
All symmetry operators are 2-folds with a transition-component. None of
them falls on a crystallographic axis.
For the symmetry operations A -> B, A -> B and A1 -> A2 I use A as mask,
for B1 -> B2 i use B as mask and for C1 -> C2 C as mask.
The question:
Are these symmetry operations enough to cover the whole symmetry?
Or do I have to specify the operations A -> C, A1 -> B1, A1 -> B2 ,...
seperately?
Thanks a lot for any suggestions
Jan
