  1. Each level corresponds to the hierarchical level in the Infomap community analysis [10]. A community at a level can be decomposed at the next lower level (from top to bottom). If a community cannot be decomposed further, it is called an irreducible community. The numbers of irreducible communities are listed in the third column. The fourth column lists the numbers of accounts belonging to these irreducible communities at each level.
