Another point that we can draw from this analysis is that the named nets, present in the RCSR, EPINET and IZA-SC topology databases, only represent of small fraction of the many topologies identified. Indeed, of the 40,246 different topologies identified in the database, only 713 have common names (1.7%). The others are labeled unnamed-n, with integer values of 𝑛 in decreasing order of frequency of their occurrence.
