# 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!!!
