A classification of two-distance-transitive Cayley graphs over the generalized quaternion groups

Wei Jin, Pingshan Li, Li Tan

A non-complete graph is \emph{ $2$ -distance-transitive} if, for $i = 1, 2$ and for any two vertex pairs $(u_{1}, v_{1})$ and $(u_{2}, v_{2})$ with the same distance $i$ in the graph, there exist…

Fault-free Hamiltonian cycles in balanced hypercube with conditional edge faults

Pingshan Li, Min Xu

The balanced hypercube, $B H_{n}$ , is a variant of hypercube $Q_{n}$ . Zhou et al. [Inform. Sci. 300 (2015) 20-27] proposed an interesting problem that whether there is a fault-free Hami…
