Tensor commutation matrices can be constructed with or without calculus. A formula allows us to construct a tensor permutation matrix, which is a generalisation of tensor commutation matrix, has been established. The expression of an element of a tensor commutation matrix has been generalised in the case of any element of a tensor permutation matrix. Some tensor commutation matrix has been expressed by using the Gell-Mann matrices.22 pagesGeneral Mathematicstext
