The Sequence in trigrams – and decades

And I thought I wrote about trigrams in the Sequence. Heh. Here’s Frank Kegan doing a very complete and insightful job of it. He sees the Sequence in groups of ten (which I’ve found works startlingly well – you might think that more patterns would emerge if you took it in eights, but that doesn’t seem to be the case at all), and goes on to describe the places within the decades with a Pythagorean system that works independently of the hexagram pairs, relying on analysing hexagrams in terms of their component trigrams. The first result is an easily understood description of hexagrams 1 to 10 as the water cycle. The rest merit further study…
