I've defined the Johnson Graph as having parameters n, and d with d ≤ n / 2. The vertices are the size d subsets of [ n] and two vertices are adjacent if and only if the size of their intersection is d − 1. I've already shown that two vertices are at distance j if the size of their intersection is d ...
