Trigram
A trigram contains three unbroken or broken lines. The eight possible combinations form the bagua.
How to approach it
The order of signs forms part of their meaning. Start with the structure and the names of its components, then compare interpretations without mixing different systems.
An important distinction
Two stacked trigrams form a hexagram; reversing their order can create a different figure.
An example to explore
Place ☰ above ☷ and then swap them: the components remain the same while the structure changes.
Taking the idea further
In this website’s application: Each throw of three coins forms one line: ☀ counts as 3 and ☽ as 2. Repeat six times, starting at the bottom. Totals of 6 and 9 are changing lines; 7 and 8 are stable. The related hexagram changes only lines valued 6 or 9. The question is optional.
