Analysis of information sources in references of the Wikipedia article "Permutation matrix" in English language version.
Let denote the set of orthogonal matrices and denote the set of element-wise non-negative matrices. Then, , where is the set of permutation matrices.
A permutation—say, of the names of a number of people—can be thought of as moving either the names or the people. The alias viewpoint regards the permutation as assigning a new name or alias to each person (from the Latin alias = otherwise). Alternatively, from the alibi viewoint we move the people to the places corresponding to their new names (from the Latin alibi = in another place.)
