Imagine a Cayley Tree, constructed starting from a central node of degree k. Each node at distance d from the central node has degree k, until the nodes reachable at distance P that have degree one, as shown in figure above. Consider k+1 communities, with communities corresponding to the subtrees rooted at the children of the central node, and the central node by itself being a community. What is the modularity of this partition if k=3 and P=4? Round it up to three decimal places.

  1. 0.523
  2. 0.621
  3. 0.785
  4. 0.891
  5. None of the above.
