  • Abstract
    The authors characterize a potentially useful set of permutation matrices that commute with the Fourier matrix of order n. The set of all such permutation matrices is a group under matrix multiplication, and every element of the group is its own inverse. They study the number of these permutations as a function of the order n_ of the Fourier matrix and conclude that it is a multiplicative function of n
