Summary of hollowness values.

Summary of hollowness values. For each dataset, we report the values of the hollowness and cycle-length normalized hollowness for cycles for real networks and their randomisations ( and ). Most networks (class I in particular) show lower values than for their randomized versions. We also report the values of the hollowness and cycle-length normalized hollowness for cycles for real networks. The values for the randomized networks are not reported as –strikingly– the randomisations do not inline any higher homology, while almost all real networks inline positive values of the hollowness.
