The number of possible person-to-person links (L) increases rapidly as the size of the group (N) increases (L = (N² - N) /2). In a four-member group there are six possible pairings; add a fifth member for each of the four to relate to and you have ten pairs. The number of possible two-person links in a group of twelve is 66.
A nation is one of the largest forms of projected or imagined community. In these terms, communities can be nested and/or intersecting; one community can contain another—for example a location-based community may contain a number of ethnic communities. [37] Both lists above can be used in a cross-cutting matrix in relation to each other.

Note that as a node can be a member of more than one clique, a node can be a member of more than one community in these methods giving an "overlapping community structure". One approach is to find the "maximal cliques". That is to find the cliques which are not the subgraph of any other clique. The classic algorithm to find these is the Bron ...
Dunbar's number has become of interest in anthropology, evolutionary psychology, [12] statistics, and business management.For example, developers of social software are interested in it, as they need to know the size of social networks their software needs to take into account; and in the modern military, operational psychologists seek such data to support or refute policies related to ...
