What is a polycule?
A polycule is the full network of relationships connecting a polyamorous person's partners, partners-of-partners, and shared relationships. The structure is often diagrammed as a graph, with nodes for each person and edges for each relationship. Polycules can be small — a triad or a vee — or large extended community networks with dozens of people connected at various levels of intimacy. The shape and stability of a polycule depends on how its members negotiate metamour relationships and shared time.
