Abstract
The burnt pancake graph B P n is the Cayley graph of the hyperoctahedral group using prefix reversals as generators. Let { u , v } and { x , y } be any two pairs of distinct vertices of B P n for n ≥ 4. We show that there are u − v and x − y paths whose vertices partition the vertex set of B P n even if B P n has up to n − 4 faulty elements. On the other hand, for every n ≥ 3 there is a set of n − 2 faulty edges or faulty vertices for which such a fault-free disjoint path cover does not exist.

- Paired many-to-many disjoint path covers in faulty hypercubes
A paired many-to-many k-disjoint path cover (k-DPC for short) of a graph is a set of k disjoint paths joining k distinct source-sink pairs that cover all the vertices of the graph. Extending the notion of DPC, we define a paired many-to-many bipartite k-...
