Median

undefined: A system with members who are not as distinct or separate from each other as in partitionary systems, and are sometimes dependent on a single individual and unable to exist without that central person. The dependence can be mutual in that there is no central individual. Median systems often consist of members who all identify as "aspects" or "facets" of one central identity, which may be a single member or may be a sort of average identity of the group.
