I think I see what you mean. Describing on object as an n-tuple suggests you can 
  say it has only intellectual value (like {0,0,0,17} ), but that's of course 
not possible since all levels are dependent on the lower levels. So if the 
supporting lower level patterns disappear, so will the higher level pattern.

But would that make the system non-orthogonal? I would rather add some kind of 
constraint to describe the special dependency in the system. Making the axes 
non-orthogonal, i.e. tilting them, would raise an impossible issue about how 
much to tilt them. It's not as if you can use the coordinate-system to calculate 
anything anyway, or?

Me too.
