Description
The Szeged index minus the Wiener index of a graph.
It is known that the Szeged index is at least as much as the Wiener index. For $2$-connected graphs on $n$ vertices, the difference is at least $2n-6$.
For the two individual statistics see St000263The Szeged index of a graph. and St000265The Wiener index of a graph..

graph of inversions
Description
The graph of inversions of a permutation.
For a permutation of $\{1,\dots,n\}$, this is the graph with vertices $\{1,\dots,n\}$, where $(i,j)$ is an edge if and only if it is an inversion of the permutation.
For a permutation of $\{1,\dots,n\}$, this is the graph with vertices $\{1,\dots,n\}$, where $(i,j)$ is an edge if and only if it is an inversion of the permutation.
