The 26x36 Solution


Here's how the final test problem was constructed.  No
complaints are allowed, for the POTM-Master is omnipotent.

1. I wanted a large number of squares ... a smaller problem
	increases the likelihood of ties which I always
	strive to avoid.

2. I wanted to be sure there was a solution that used most
	of the squares for the same reasons.  
	In retrospect, It would have been hard to avoid having
	a large solution - but perhaps that's the subject of
	another POTM!

3. So.  I constructed a quilt with the word POTM in it
	(written in black on a white background in very
	jagged lettering).  It so happened that the quilt
	was 36 squares wide by 26 tall for a total of 936.

4. Then I took the white edges of the 936 squares and 
	randomly assigned colors to them so that they
	would continue to fit together.

5. Just for fun, I added 25 more squares - each of which
	was a single color - thus arriving at a total of
	961 squares to work with.  (Coincidentally, 31*31
	is 961, but I have no idea if such a quilt is
	possible as I'm writing this on 11/24/98!)

6. Next step was to randomize the rotations.  I decided to
	leave them in the original order since it was a
	pain in the neck to "shuffle" them.  As a result,
	the 36x26 solution I started with uses the squares
	in order from 1 to 936.

Well ... that's about it ... I wondered if there's anything
better than the 36x26 solution buried in the squares!!!
