Abstract

In this paper, we consider the stack layout of the bubble-sort graph. The bubble-sort graph is a type of Cayley graph on a symmetric group; the bubble-sort graph has an important role for the study of Cayley graphs as interconnection networks. The stack layout and the queue layout problem that are treated in this paper have been studied widely. In this paper, we show that the stack number of the bubble-sort graph BS(n) is either n-1 or n-2. In addition, we show that an upper bound of the queue number of BS(n) is n-2.
