Function knn (dark point series) for a “maximally disassortative” network with 2500 nodes (r≃−0.32) obtained in the configuration model by a rewiring process which minimizes the assortativity coefficient r, starting from a BA2 degree distribution. The light point series represents, as in Fig. 4, the function knn of an ideal BA2 (r≃−0.10). The hubs of the configuration model network are generated with the “random hubs” method. For the largest hubs of the maximally disassortative network one has knn=2 exactly, implying that all their nearest neighbours have degree 2
