Earlier, for odd $n$, the author described unitary $n\times n$ matrices $U$ with the following property: if $H$ is a Hankel matrix, then $U^*HU$ is a Hankel matrix as well. In the present paper, it is shown that this description also holds for even $n$ starting from $n = 4$.
Keywords: Hankel matrix, unitary matrix, backward identity matrix, similarity transformation.
Mots-clés : automorphism, Klein four-group
