The generalization to radix representations, for , and to , is a digit-reversal permutation, in which the base- digits of the index of each element are reversed to obtain the permuted index. The same idea can also been generalized to mixed radix number systems. In such cases, the digit-reversal permutation should simultaneously reverses the digits of each item and the bases of the number system, so that each reversed digit remains within the range defined by its base.
