For example, in Figure 1 we show all the non-isomorphic directed subgraphs of size 3. These subgraphs differ from each other in the number of edges or direction of edges.

Network motifs are recurring, significant patterns of interconnections in the network. Here, pattern means it is small induced subgraph. Note induced subgraph of graph G is a graph formed from a subset X of the vertices of graph G and all of the edges connecting pairs of vertices in subset X.
