One of Euler's knight's move squares

If I remember correctly, I asked this question years ago, but even if I did, I'll never find it now. Can anyone help to find the appropriate link to this particular Euler's square on the internet, please? I'm slowly trying to update my web site and I refer to this on the Interests page. Any help will be much appreciated.
