There’s a similar application of the Enneagram, but to body types. Rodney Collin is a source for these ideas. Joel Friedlander and Susan Zannos have written books on this version of the Enneagram.

Another application of the Enneagram is as part of a pantheon of systems – from monads, dyads and triads through to larger systems. John Godolphin (J. G.) Bennett was key in developing these ideas and their application to life situations. He used the term Systematics (also used in Biology, but with a different meaning). Two of his books that are relevant are Elementary Systematics / A Tool for Understanding Wholes and Enneagram Studies. Bennett had ties to Gurdjieff, who introduced the Enneagram to his students.

Bennett’s ideas on Systematics have been applied in business situations. See Saul Kuchinsky’s Systematics / Search for Miraculous Mangement and Richard Knowles’ The Leadership Dance / Pathways To Extraordinary Organizational Effectiveness. Saul died some years ago; go to www.centerforselforganizingleadership.com/ to contact Richard and his wife. Tell them I sent you.

Here’s a picture of the Enneagram, with a red circle at the top that I added to fit it into the N-Gram diagrams I developed. They are based on the way the patterns of repeating digits in base ten for n/7 (.00, .142857, .99) and n/3 (.oo, .33, .66, .99)  are represented in the Enneagram, but with other divisors in addition to 3 and 7, and applied in other bases in addition to ten.
