Abstract
The Johnson graphs J(n, k) are a well-known family of combinatorial graphs whose applications and generalizations have been studied extensively in the literature. In this paper, we present a new variant of the family of Johnson graphs, the Full-Flag Johnson graphs, and discuss their combinatorial properties. We show that the Full-Flag Johnson graphs are Cayley graphs on \(S_n\) generated by certain well-known classes of permutations and that they are in fact generalizations of permutahedra. Our main result will be to establish a tight \(\varTheta (n^2/k^2)\) bound for the diameter of the Full-Flag Johnson graph FJ(n, k).
