Talk:Bisymmetric matrix

I recently have been working with symmetric Toeplitz matrices and noticed that it's invertible matrix always happens to be bisymmetric. Maybe should add this fact to the article? I'm sure someone had proven this already.136.169.154.36 (talk) 08:34, 21 January 2014 (UTC)
 * Symmetric Toeplitz matrices are bisymmetric matrices, and the inverse of any non-singular bisymmetric matrices is bisymmetric. This is a consequence of the fact that the inverse of a non-singular symmetric matrix is symmetric and that the inverse of a non-singular centrosymmetric matrix is centrosymmetric. &mdash; Myasuda (talk) 14:17, 21 January 2014 (UTC)
