A segment cluster represents the group of segments of which a particular person is a member. For example,

Segments B and D are a bold cluster, while C and E are an Italic cluster. There are 2^5 possible combinations of two segments in this example; each potential cluster must have a unique name.

Since a person can belong to multiple segments, reporting sales by segment alone can give deceptive results. Segment clusters show how users group themselves.
