The 9th Wing of the “Ten Wings” (a collection of texts about the I Ching, attributed to Confucius) is a short text that shows in which order the hexagrams follow each other.
However, a grave library was discovered in 1972 in Mawangdui, which also contained a copy of the I Ching, which is much older than the text known so far. This version of the I Ching differs from the previously known text by about 25%, among other things in the order in which the hexagrams follow each other.
