A Network Motif
A recurring, statistically significant subgraph or pattern within a larger network graph, commonly found in various types of networks including biological, social, and technological systems. They are considered the building blocks of complex networks, appearing more frequently than would be expected in random networks. Network motifs can serve as elementary circuits with defined functions, such as filters, pulse generators, or response accelerators, and are thought to be simple and robust solutions that have been favored by evolution for their efficiency and reliability in performing certain information processing tasks.

Example
A network motif example is the small-world network, which is a type of network that has both highly connected clusters and short paths between distant nodes, allowing for efficient information transfer. This motif is often observed in biological systems, such as the neural networks of animals, and can also be found in social networks and other complex systems.
