Sung: Part II - Their Exibits

Chapter VI - The Trigrams and Hexagrams

This chapter contains some of the cubic hexagram space diagrams again. In the figures on p96 and p97 in particular the author implicitly identifies that the corners encode the hexgrams formed from doubled trigrams. The diagram from p96 is shown below.

From Z.D. Sung, p96

The figures are apparently concerned with how one hexagram changes into another, but it's hard to see what the geometry adds.
