Abstract :
It is shown that by exchanging any two independent edges in any shortest cycle of the n-cube (n⩾3), its diameter decreases by one unit. This leads to the definition of a new class of n-regular graphs, denoted TQn, with 2n vertices and diameter n-1, which has the (n-1)-cube as subgraph. Other properties of TQn such as connectivity and the lengths of the disjoints paths are also investigated. Moreover, it is shown that the complete binary tree on 2n-1 vertices, which is not a subgraph of the n-cube, is a subgraph of TQn. How these results can be used to enhance hypercube multiprocessors is discussed
