Collaboration \(K_7\) graph

We define the collaboration graph \(G\) of the research group as follows. The graph \(G\) has as vertices all members of the research group and all co-authors of the members, with an edge joining \(u\) and \(v\) if \(u\) and \(v\) have published a joint paper. The maximal complete subgraph of \(G\) is isomorphic to \(K_7\).
Labels indicate the number of joint papers.
Blue numbers denote special article.
Green numbers denote work in progress papers.
