What is the official notation (and the source of the notation) of the following permutations matrices (one shift left of identity matrix):

For $n=2$

$P = \left(\begin{matrix}0 & 1\\ 1&0\end{matrix}\right)$

For $n=3$

$P = \left(\begin{matrix}0 & 0 & 1\\ 1 & 0 & 0 \\ 0 & 1 & 0\end{matrix}\right)$

    You may borrow the notations from permutation group https://en.wikipedia.org/wiki/Permutation_group – Ziyuan Sep 05 '13 at 09:47
  • $P$ stands for Permutation, I think. Unfortunately, somtimes $P$ stands for other matrices as well, i.e., for alternating sign matrices: http://en.wikipedia.org/wiki/Alternating_sign_matrix. – Dietrich Burde Sep 05 '13 at 11:56
