A simple graph, as opposed to a multigraph, is an undirected graph in which both multiple edges and loops are disallowed. In a simple graph the edges form a set (rather than a multiset) and each edge is an unordered pair of distinct vertices.
A clique is a set of vertices of a graph, each pair of which is joined by an edge and no set containing this set has this property. In a simple graph, the subgraph induced by a clique is a complete graph. Neighborhoods. Any pair of adjacent vertices in a graph are called neighbors.
