The I Ching dates from 400 BC. The text of the I Ching is a set of oracular statements represented by a set of 64 abstract line arrangements called hexagrams (卦 guà). Each hexagram is a figure composed of six stacked horizontal lines (爻 yáo), where each line is either Yang (an unbroken, or solid line), or Yin (broken, an open line with a gap in the center). With six such lines stacked from bottom to top there are 2^{6} or 64 possible combinations, and thus 64 hexagrams represented.
The King Wen sequence is the traditional (i.e. "classical") sequence of the hexagrams used in most contemporary editions of the I Ching. The King Wen sequence has been shown to contain within it a demonstration of advanced mathematical knowledge.
In his article Explication de l'Arithmétique Binaire (1703) Gottfried Leibniz writes that he has found in the hexagrams a base for claiming the universality of the binary numeral system. He takes the layout of the combinatorial exercise found in the hexagrams to represent binary sequences, so that ¦¦¦¦¦¦ would correspond to the binary sequence 000000 and ¦¦¦¦¦ would be 000001, and so forth.
The same binary system underlying the ancient and mystical I Ching sequence forms the basis of modern computing.
