What this part means

The expressions on both sides represent the same quantity under the stated assumptions.

Its job in the formula

The equals sign connects the complete expression on the left with the complete expression on the right. Both sides must have compatible units.

The passage around this formula

For n agents that each need a channel to every other agent, the number of pairwise links a fully connected coordination topology requires is (n2)=n(n−1)2\binom{n}{2} = \frac{n(n-1)}{2}. which grows quadratically in n even before accounting for the content sent over each link. That is a modeling assumption, not a law of nature — a system that routes all communication through a single orchestrator instead of a full mesh pays a linear cost in links, at the price of a central bottleneck and a single point of failure — but every real multi-agent framework has to choose a point on that trade-off, and reasonable designers disagree about where: full-mesh topologies keep no single node load-bearing but scale their wiring…
