In the context of Cayley graphs, the diameter of a graph is defined as the greatest distance between any pair of vertices. This means it measures how far apart the two most distant points in the graph are, which provides insight into the overall structure and connectivity of the graph. The diameter plays a crucial role in understanding the efficiency of navigating through the graph, as well as its properties related to the underlying group it represents.
congrats on reading the definition of Diameter. now let's actually learn it.
