Despite not posting anything here I have been busy this month, but not making much progress.
Partly this is because I've had trouble with blisters on a leg and losing a couple of front teeth, so have been kept occupied visiting dentist and GP surgeries and hospital for checkups.
I'm still trying to complete my study of the Onitiu Problem but am stuck on the 14x14 case.
I'm also trying to edit my 12 PDFs on Knight's Tours into a shorter book.
Another project is a book on Numbers, which I may call Numerology or maybe Arithmology, with the subtitle The Wisdom and Folly of Numbers, .since it includes chapters on Arithmosophy and Numeromancy. It also includes my notes on Figurate Numbers as well as basic Arithmetic.
