Abstract
This paper introduces a simple O(NlogN) sequential algorithm that determines the admissibility of an arbitrary permutation to an N×N Multistage Cube-Type Network (MCTN) implemented by 2×2 switching elements (SEs) in contrast to previous O(Nlog2N) algorithms. It is proven that the new algorithm is optimal in the sense that any algorithm, based on bit-operations, has to examine at least (N/4)logN different bits among the total NlogN bits in the binary representations of the destinations numbered from 0 through N-1
