Figure 3. Graphlets, automorphism orbits, and GDVs.

Figure 3

(A) All 9 graphlets with 2, 3 and 4 nodes, denoted by Inline graphic, Inline graphic,…,Inline graphic; they contain 15 topologically unique node types, called automorphism orbits, denoted by 0, 1, 2, …, 14. In a particular graphlet, nodes belonging to the same orbit are of the same shade (see [47] for details). (B) An illustration of the GDV of node Inline graphic; it is presented in the table for orbits 0 to 14: Inline graphic is touched by 4 edges (orbit 0), end-nodes of 2 graphlets Inline graphic (orbit 1), etc. The figure is taken from [53].
