Subject: RE: math behind a puzzle

I have an actual blind friendly hardware puzzle I bought at CSUN.  What
ticks me off is I know how to do the thing but it takes me forever.  My wife
on the other hand sits down and goes blink blink blink and done.  Grrrr.  If
you're interested in buying one let me know I will dig up the place that
sells them.  They have Braille squares so you can feel them and you can get
a couple types some have numbers some have words.

Ken

I get a sense of the puzzle's components, but I don't follow what
actually constitutes solving the puzzle. Can you be a little more specific?
