The densities as respects their sub-densities

[Lighthead]

I re-read your question. I do not think the 6th sub-density of 3D has the same meaning as 6D itself. It is more like the 6th level of the sub-strectrum.

Ra gave the analogy of music, I'm no music expert but if you take the C note which is the first note of a C range. And extend the spectrum of that note into 7 sub-notes, you wouldn't get a A note (which is the 6th note of the range) as the 6th sub-note.

Not sure if this will make sense to you.

I understand. But the topic in general is hard to understand. I wish we could hear from an expert. Either anagogy or Tan.
