Knight's Tour Notes

I've opened this site, September 2008, as a new home for my study of Knight's Tours since, due to problems with my computers, I have for some time been unable to access the old dial-up site at FreeUK, and so have been unable to keep it up to date. In due course I propose to bring all the data from the old site here, but recast in an improved style.

A New Beginning

To begin, here is a file that has been on hold for some time. Style updated August 2009, but some diagrams still missing. This subject received some mention in Variant Chess #58 (October 2008).

Magic Torus Tours

New August 2009: Here's another essay based on work mostly done back in 1995, but now rechecked.

The Smallest Knight-Tourable Boards

Added March 2010: A page on Non-intersecting knight paths in KTN is based mainly on work by Robin H. Merson, who died in 1992, but does not include all his results. Accordingly I am including here PDF copies of the letters and accompanying diagrams that he sent to me in 1990 on open paths and 1991 on closed paths. Where red ink is referred to this is mostly the first figure cited.
