Large, well-connected nodes have more links to each other than to smaller nodes, and smaller nodes have more links to the larger nodes than to each other.
The researchers found that 27 percent of connections are among the largest five percent of nodes, 60 percent connect the remaining 95 percent to the largest five percent, and only 13 percent of connections are between nodes not in the top five percent.
