Xor Rotation Group Index
The rotation of the symbol rings always flips the bit. This operation is defined recursively as follows:
P _{X}> 0 = P.
P _{X}> n = ((P >> 1) x ) _{X}> n1
That is, after an ordinary rotation, the bottom line of the result is changed.
Period = 4
P _{X}> 0 =
Period = 12
P _{X}> 0 = Waxing and Waning of the Seasons
P _{X}> 0 =
P _{X}> 0 =
P _{X}> 0 =
P _{X}> 0 =
Mondo Secter refers to these groups of hexagrams as "evolutionary cycles" of hexagrams. See pages 6163 of his book The I Ching Handbook. Here I arrived at them via the formal algebraic description of the traditional seasonal cycle of hexagrams.
