      I was quite wrong about the Golden Mean and 7 x 3 classification. The golden ratio is approximately 1.6180339887. In architecture and the arts it has been the formula for harmony since at least the time of the semi-mythical mathematician, Pythagorous (circa 800 BC). Is 7 x 3 classification perhaps of more interest to mathematicians than taxonomists? However, I wonder if the Golden Mean might have some application in our world? It is about shapes, and what taxonomies do is shape information.

      When I first read "7x3," I thought, immediately, that
      it was a reference to facets and orthogonality. But,
      more to the point, I would think, at the least, that
      any numbers related to describing the structure of a
      given vocabulary would, in great part, indicate the
      adequate to thorough coverage of a domain.

      It seems that applying the "7x3" or "7 + or -2" rules
      focuses primarily on, or biases in favor of, the user
      at the risk of losing sight of content warrant.
