Hi MathsIsFun;

Thanks for providing that! There is a link to his paper at the bottom. Also, it will eventually take you to the Electronic journal of combinatorics.

**In mathematics, you don't understand things. You just get used to them.I have the result, but I do not yet know how to get it.All physicists, and a good many quite respectable mathematicians are contemptuous about proof.**

When I worked in produce, the oranges came 72 or 113 in a box.

I used to sift thru IEEE journals from the 1920's to the present on logic circuits, talking about combinatorics.

Once I ran into a neat algorithm using XOR gates that I could not comprehend though.
