- Three line types across four positions form eighty-one heads.
Definition and details
Yang Xiong’s text uses three forms rather than the Zhouyi’s binary lines. Four positions yield three to the fourth power, or eighty-one combinations. Heads contain statements with explanatory ce passages. Combinatorial counting is directly checkable, but each combination’s meaning requires reading its words; knowing the total does not establish the text’s entire philosophy.
Structure and history
As a Han intellectual and numerical text, it adapts classical forms while developing its own vocabulary. Transmitted witnesses include commentary associated with Fan Wang and others, requiring separate labels. Taixuan figures are not alternate fonts for sixty-four hexagrams, and modern Unicode glyphs alone cannot establish a unique ancient written or printed appearance.
A concrete example
The first head, Zhong, provides nine positions with corresponding explanations. Label the sequence from its first to ninth statement, examine changing wording within the head, then compare the next, Zhou. This reveals textual hierarchy without transferring historical terms of esteem or inferiority into judgments about a real person’s ability or social worth.
Context and limits
The work combines cosmic, temporal and behavioral reflection rather than merely offering random oracle quotations. Comparison with the Yi needs explicit line types, positions and interpretive units. A clear mathematical structure does not validate fortune judgments; check witness and glyphs, and consult scholarship for contested temporal or philosophical interpretations instead of claiming a universal natural law.
References & further reading
Historical sources document ideas and rules of their time, not empirical proof of predictive accuracy. Source notes identify the nature and scope of each reference.
