to a pdf document. And to uncompress the gz file you can either search for gzip (gunzip) or use Cygwin so you can have the full Gnu suite available. There is a gzip for windows, but I am a little confused, because I thought 7-Zip is able to expand the GZip
files.<o:p></o:p></span></p>

Reminds me of a very fascinating paper<br>
<a href="http://www-cs-faculty.stanford.edu/~uno/papers/dancing-color.ps.gz">http://www-cs-faculty.stanford.edu/~uno/papers/dancing-color.ps.gz</a><br>
<br>
(Note that the paper discusses puzzles where pieces may have one out<br>
of a limited number of "shapes" resulting from all permitted<br>
positions. I guess that's similar to what OP described.)<br>
