Abstract:
Generating a random permutation by arranging a sequence N numbers in a matrix, performing random arrangement operations on the rows of the matrix to generate an intermediary matrix, performing random arrangement operations on the columns of the intermediary matrix to generate a second intermediary matrix, and arranging the N numbers of the second intermediary matrix as a rearranged sequence of the N numbers.
