Each vertex is a permutation of integers 1..5, so 5!=120 vertices. Each edge is by swapping elements to reach a lexicographically bigger permutation, and where not already reached by some longer chain of transpositions (so Hasse diagram, equivalent to number of "inversions" increase by 1). Number of edges 444 is OEIS A002538.
