Up: Four orbits with different color. Down: The computation of GDV for node \(\nu\) in graph \(\mathcal {G}\). This diagram illustrates all instances where node \(\nu\) appears in four distinct orbits. Correspondingly, the GDV for \(\nu\) is [2, 1, 0, 1], reflecting the appearance count of \(\nu\) in these orbits.
