This chapter discusses subgraphs in complex networks. First, it considers ‘building blocks’ of networks-motifs subgraphs that are present in many copies in a network. It focuses on the statistics of cliques and motifs in complex networks. It also discusses ways to detect relatively weakly-interconnected modules in a network (communities) and introduces the notion of modularity.

Keywords: motifs; subgraphs; modularity; cliques; communities; hierarchical organization
