The Buckingham Clique

The Buckingham Clique is a concept from graph theory that refers to a group of nodes (or vertices) in a network where every node is directly connected to every other node in that group. Imagine a fully connected team where everyone knows each other personally—this tightly-knit group is called a clique. The Buckingham Clique specifically highlights such complete subgroups within larger networks, emphasizing strong mutual relationships. It is useful in analyzing social networks, communication patterns, or any interconnected system where understanding closely linked clusters helps reveal underlying structure and dynamics.
