On fault tolerance of (n,k)-star networks

Fault tolerance of an (n,k)-star network is measured by its h-super connectivity κs(h) or h-super edge-connectivity λs(h). Li et al. (2014) [8], (2012) [6] determined κs(h) and λs(h) for 0≤h≤n−k. This paper determines that κs(h)=λs(h)=(h+1)!(n−h−1)(n−k)! for n−k≤h≤n−2.
