Depicts a method of contructing a well-connected network from smaller networks. FRONT VIEW: In each small network of 4 nodes, and in the large network of 5 small networks (that substitute for nodes), each node connects directly to all others. Each node connects to one other small network. Combined, each of 20 nodes connects to all others with no more than 3 connections. BACK VIEW: Same idea, but 7 small networks of 3 nodes each. Each node connects to TWO other small networks. GENERAL: Both have 4 connections per node, and maximum distance of 3 connections. But it's possible to make a larger network (of 29 nodes) with these properties.
