1. A process of forming a control bit table for a routing multiplexer that provides p outputs based on a selected permutation of p inputs, the process comprising steps of: a) defining the selected permutation having a length n, where n>p; b) identifying first and second groups of vertices each containing alternate vertices of a graph of the selected permutation; c) calculating first and second permutations based on respective first and second groups of vertices; and d) forming the control bit table based on the first and second permutations and on the vertices of the graph of the selected permutation.
