Hi Armand,
Thanks for the advice.
Well I managed to open the gz file with another decompression tool. No idea why 7-zip did not manage.
I'll try to convert it with that ps2pdf tool.
Thanks!

.ps.gz is a postscript file compressed using GZip. On windows you will need to find a postscript viewer, or you can use the ps2pdf online tool to convert it
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.

Thanks a lot.
Though when I try to open the archive with 7-Zip it says that it cannot open it.
I'm working on Windows7.
Any idea of tool I could use?
Thanks

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