Hypercube embeddings and Cayley graphs generated by transpositions
A graph is called a partial cube if it can be embedded into a hypercube isometrically. In this paper, we study a class of Cayley graphs —Cayley graphs generated by transpositions and show that a Cayley graph Γ generated by transpositions is a partial cube if and only if Γ is a bubble sort graph. This result enhances a result of Alahmadi et al. [Math. Meth. Appl. Sci. 39 (2016), 4856–4865]: BS is a partial cube. As a corrollary, we give the analytical expressions of the Wiener indices of bubble sort graphs.
