Hello again,

     First of all, thanks to those who were kind enough to try my  
little puzzle.  I don't think its worth too much time, but I will  
elaborate a bit on what I have in mind by elegant.
     Some years ago, at the annual Mathematica convention in Urbana, someone  
sponsored a contest with prizes  for the "best" solution to a  
programming problem.  One of the puzzles had to do with transforming  
a list of zeros and ones into a significantly shorter list containing  
the same information but in more compact form.  This process is now  
automated by the command Encode (I believe).  I was new to Mathematica at the  
time and was very impressed by the ingenuity shown by the experts.    
I was hoping that my problem which is in essence a transformation by  
summation-by-parts might be amenable to a similar stroke of  
programming brilliance.
     As I mentioned in my first post, the problem is relatively easy  
to do by straight-forward, some might say brute force, methods.
     In any case, thanks again.  Always a pleasure to see how many of  
you guys are willing to spend time to read our questions and respond  
with insightful ideas.

Jack
