I Ching Related Hexagrams (互錯綜交) (易經互錯綜交卦)

I Ching Related Hexagrams — the classical way to read any hexagram in depth, through its four transformations. From a hexagram (a King Wen number or six lines) it derives the 互卦 (nuclear — built from lines 2·3·4 and 3·4·5, the hidden inner process at the core), the 錯卦 (opposite — every line inverted, the complementary shadow / opposite standpoint), the 綜卦 (reversed — the hexagram turned upside-down, the view from the other party's side; for the eight line-symmetric gua the 綜 is itself and the 錯 carries the pair instead), and the 交卦 (swapped — upper and lower trigrams exchanged, the two forces reversed), plus the 之卦 from any moving lines. Each related hexagram returns its King Wen number, name, six lines and trigram breakdown. Deterministic bit-transforms on the standard King Wen sequence — the transformations are exact, the meanings a traditional interpretive framework, not a validated predictor.
