Hello Robert, sorry to be unclear, the "words" alone have to be found, not the path linking them. So you can find "0", of course, "1", "2", etc. And "10", "11", "12"... But for "19" (in my example) you have to add an extra digit "1"... Hope I'm more clear now, E. -------- Message d'origine-------- De: math-fun-bounces@mailman.xmission.com de la part de Robert Munafo Date: jeu. 22/07/2010 00:10 À: math-fun Objet : [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.

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 .
