Knight's Tours Again

I've been making some progress in organising my files on Knight's Tours into publishable form. It is taking the form of a series of separate "Studies", each of about 60 pages, covering a particular topic. These are at present: History, Theory of moves, Leaper tours, Knight on 6x6 board, Knight on 8x8 board, Knight on other rectangular boards, Shaped and holey boards, Figured and magic tours. I should be able to make these available in PDF form, if not as a book.

We had two three or four-hour power cuts here over the past two weeks. The first one on Thursday 3rd September 5-8pm was without warning but the other on Friday 11th September 11am-3pm was notified by the electric company EDF. I took the opportunity to give my refrigerator a thorough defrosting and clean. Fortunately I had kept a supply of matches to light the gas, and have a supply of candles somewhere in case of emergency, but not needed on this occasion.
