One of my main interests for many years has been in mathematical recreations, as will be evidenced by my Mayhematics pages, although I've not done much original work lately. However, I would like to get back to doing some.
Recently I have been receiving emails from various people active in mathematical recreations, who are furthering some of the subjects that have particularly interested me in the past. I give here some links to websites showing their work.
The following are investigating magic knight's tours on three dimensional boards, among much else: Aale de Winkel, Awani Kumar, Harvey Heinz and Francis Gaspalou.
I have also heard from Vaclav Kotesovec who is studying leaper and hopper tours, revisiting work done by myself and T. H. Willcocks in my magazine Chessics as far back as 1976. In particular he has constructed a 64-cell closed grasshopper-over-knight tour. It begins with Grasshopper a1 and Knight f6 and ends with the Grasshopper back at a1 and the Knight at b1.

Hi George,
ReplyDeleteWhat is stopping you from getting back to your old love, that is, mathematical recreations. We are anxiously awaiting you.

My old brain is not what it was.
