N is the network size. |E| is the number of edges. d is the diameter. L is the average shortest path length. µ is the density. and are, respectively, the unweighted and weighted average clustering coefficients. λ and represent, respectively, the unweighted and weighted assortativity, also called the degree-degree correlation coefficient. η is the hub dominance.
