TITLE: Union of differences between three sets, where nothing intersects, how is it called?
QUESTION [23 upvotes]: I'm trying to find how to express the following:

I think it would be something like:
$$(A - (B \cup C)) \cup (B - (A \cup C)) \cup (C - (A \cup B))$$
But does this have a name? A simpler way to express it? Since this expression grows fast while one add more sets.
