[math-fun] King walk on a square grid to write 0 to 100

In your example, I can't even get from 8 to 9! It looks like I have to start with the 0 in the 2nd row, and I find only one choice at each step up to 8. So I end up at the 8 in the 2nd row and there is no adjacent 9. On Wed, Jul 21, 2010 at 15:34, Eric Angelini <Eric.Angelini@kntv.be> wrote:

What would be a "minimal king's-tour spelling matrix" showing all integers from 0 to 100?

Double digits can be accomodated by the rule that a cell may be counted twice.

The attempt below is for sure not minimal (minimal = quantity of cells = 24, here):

9 2 3 4 7 8 9 4 7 8 0 5 3 . 0 6 1 2 9 1 . . 5 4 3 6 4 .
