The diagram below is from I Ching Mathematics: The Science of Change.
It illustrates the eight pairs of hexagrams that derive from the initial “Predictive” pair obtained by divination via coins or yarrow stalks or random number generators.
Each of the rectangles in this diagram, therefore, represents a pair of hexagrams to be analyzed according to its interpretive function (Constructive, Metamorphic, etc.).
The mathematical calculations—all of which derive from the divinatory hexagram and its line changes—are detailed below their respective functions.
