Abstract


This article discusses the permutation matrix which is a weak commutation matrix. This weak commutation matrix is determined by compiling the duplicate entry in the main diagonal, i.e., two, three, and four which are the same in different positions. The method for determining this matrix is to use the property of  the transformation  matrix to  transpose the matrix.  Based on this, we have 24 weak commutation matrices for the matrices.

Keywords
