Abstract I Ching's Symmetry - Both sides of the story

The I Ching cut diagonally to show that the opposite side of the I Ching shows the

same numbers but in reverse for example my own 1/7 is in the opposite position

to 7/1 so if the I Ching was folded over you could read 1/7 on one side flip it over

and you have 7/1 instead. You only ever need to know half the story to see the

whole picture. At the diagonal just one triangle shows a single number and the

opposite side also shows the same number as a single.

The image below shows the half version in another form fold it down

the middle and you have the same numbers appearing on each side. 

Its all you need ...
