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 TQ n, with 2n vertices and diameter n -1, which has the (n -1)-cube as subgraph. Other properties of TQ n 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 TQ n. How these results can be used to enhance hypercube multiprocessors is discussed
