Given N possibly overlapping sets, give formulas that specify, using intersections and complements of the given sets, N disjoint sets with the same union as the original N sets. The sets that result are to be the same as the given sets in the case where the given sets are already disjoint.
(In reply to re(2): Suggestions from Proposer
The following sets:
are pairwise distinct, are they not?
There are only 4 possible disjoint sets here (5 if one counts the null set); is that not right?
