The I Ching hexagrams don't represent numbers. They're not ordered numerically and any of the traditional sequences and they're not used to perform arithmetic.

The I Ching hexagrams don't represent numbers. They're not ordered numerically and any of the traditional sequences and they're not used to perform arithmetic. The individual lines represent (AFAIK) 2's, 6's, 3's, and 9's depending on whether the line is male or female, moving or static. The correspondence between the hexagrams and the binary numbers nothing more than a necessary consequence of the representation chosen: the number of states of a string of 6 characters in a system of 2 symbols.
