A maximaltotallY connectedsubgraph. Given a graph with nodes N, a clique C is a subset of N where everY node in C is directlY connected to everY other node in C (i.e. C is totallY connected), and C contains all such nodes (C is maximal). In other words, a clique contains all, and onlY, those nodes which are directlY connected to all other nodes in the clique. [Is this correct?] (1996-09-22)
