This paper addresses the fundamental problem of permuting the elements of an array of $n$ elements according to some given permutation. Our goal is to perform the permutation quickly using only a polylogarithmic number of bits of extra storage. The main result is an algorithm whose worst case running time is $O(n \log n)$ and that uses $O(\log n ...

Array Permutation by Index-Digit Permutation
Journal of the ACM, 1976An array may be reordered according to a common permutation of the digits of each of its element indices. The digit-reversed reordering which results from common fast Fourier transform (FFT) algorithms is an example. By examination of this class of permutation in detail, very efficient algorithms for transforming very long arrays are developed.

In this paper the construction of a switching network capable of n !-permutation of its n input terminals to its n output terminals is described. The building blocks for this network are binary cells capable of permuting their two input terminals to their two output ...

The group \(\hbox{Sym }\mathbb{R}\) of permutations of the set \(\mathbb{R}\) of real numbers is considered in the paper. Let \(P_ 0\) be its subgroup of power functions \(x\mapsto x^{m/n}\) where \(m\), \(n\) are positive odd integers, \(T\) be the subgroup of translations \(x\mapsto x+a\) where \(a\) is a real algebraic number, and \(M\) be the ...
