Abstract
The Birkhoff polytope graph has a vertex set equal to the elements of the symmetric group of degree $n$, and two elements are adjacent if one element equals the product of the other element with a cycle. Maximal and maximum cliques (sets of pairwise adjacent elements) and independent sets (sets of pairwise nonadjacent elements) of the Birkhoff polytope graph are studied. Bounds are obtained for different sizes of such sets.
