Yes, in particular, whilst it seems self-evident that all such examples 
must consist of sets of n bells, where each set follows the same path, 
and the n bells within each set follow the same path offset from each 
other, are there any examples where the the bells within a set are not 
in some sense contiguous, i.e. the structure is not reducible to a 
principle on M/n bells?
