Actually Schwartz is the union of such sets. There can be more than one,
such as when all the candidates are tied with each other.

You can also say that Schwartz consists of every candidate who has a
path of pairwise victories leading to any candidate who defeats him.

Suppose A-B and B-C are tied, but A defeats C. Then the Smith set contains
all three candidates while the Schwartz set only contains A and B.
