Example 1.10. There are six different 3 × 3 permutation matrices, namely ⎛ ⎝ 1 0 0 0 1 0 0 0 1 ⎞ ⎠, ⎛ ⎝ 0 1 0 0 0 1 1 0 0 ⎞ ⎠, ⎛ ⎝ 0 0 1 1 0 0 0 1 0 ⎞ ⎠, ⎛ ⎝ 0 1 0 1 0 0 0 0 1 ⎞ ⎠, ⎛ ⎝ 0 0 1 0 1 0 1 0 0 ⎞ ⎠, ⎛ ⎝ 1 0 0 0 0 1 0 1 0 ⎞ ⎠. (1.30) These have the following effects: if A is a matrix with row vectors r 1, r 2, r 3, then multiplication on the left by each of the six permutation matrices produc...
