A103314 conjecture

[David Wilson]

Right now, I am inclined to believe that if S is a zero-sum subset of the 
nth roots of 1, that n can be built up from (zero-sum) cyclically balanced 
subsets via the following operations:

1.  A U B, where A and B are disjoint.
2.  A - B, where B is a subset of A.

If this were proved, it might allow us to make some headway against a 
general formula for A103314.

Can anyone comment?
