The King Wen Sequence

Understand the received 1–64 hexagram order, its exact reversal-and-complement pairings, its unresolved history, and how IChingAsk uses it.

What the name identifies

In IChingAsk, ‘King Wen sequence’ means the received order used for standard hexagram numbers: Qian is 1, Kun is 2, and Jiji and Weiji are 63 and 64. The name is a conventional label, not a verified claim that King Wen designed the order. A number identifies a place in this received text; it is not a date, rank, or prediction.

Start with thirty-two pairs

Read the order as adjacent odd-and-even pairs: 1/2, 3/4, through 63/64. In twenty-eight pairs, reversing the six line positions of the odd-numbered figure produces its even-numbered partner. Reversal changes bottom-to-top position; it does not by itself change yin into yang.

Four pairs use the complement rule

Hexagrams 1, 27, 29, and 61 are unchanged when their line positions are reversed. Their partners (2, 28, 30, and 62) therefore flip all six polarities instead. These are the four self-reversing exceptions to the reversal rule. Some other reversal pairs also happen to be complements, so complement and reversal are distinct operations that can coincide.

The full rationale remains unsettled

The pairing rule is exact, but it does not derive the order of all thirty-two pairs or prove why each member comes first. The Mawangdui manuscript preserves the same sixty-four-state system in a substantially different trigram-based order. No source used here identifies the received sequence’s author, precise completion date, or one accepted design formula.

A concrete comparison with Mawangdui

The silk manuscript begins with the figures numbered 1, 12, 33, 10, 6, 13, 25, and 44 in the received order. They share Qian as their upper trigram. Each group begins with a doubled trigram, then combines that upper trigram with the other lower trigrams in a prescribed order. This is why a citation by manuscript position needs a cross-reference: the manuscript’s second figure is received Hexagram 12, not received Hexagram 2. IChingAsk keeps received numbering throughout.

What the Xugua explains

The received Xugua commentary reads the order as a chain of named conditions: one situation is said to give rise to the next. It is a historical interpretation of succession and can be read on those terms. It is not a construction record, and its thematic links do not establish that the sequence predicts a person’s next event.

How IChingAsk uses the order

The Library opens in King Wen order, sorting all sixty-four hexagrams by their received numbers. Previous and next follow that textual order. Inverse, complement, nuclear, and moving destinations are computed separately from the six lines. Trigram pairs, binary, and balance orderings rearrange the same cards without changing their numbers, slugs, or texts.
