Map 692 The Shape and Directions the Crystals take

This is a map showing the crystal and how they take different directions of movement which again may help us to decide why the Alerts are different.

The horizontal bar of the 8/4 crystal also holds two alert points.

The alert points in the 8/4 and diamond crystal are at the centre points of the crystal and associated with the numbers in a combination of 3, 4, 7 or 8. Whereas the double crystal alerts are associated with centre based letters C or G or the numbers 3/3,  4/4, 7/7 and 8/8 not a combination but both the same number.

Based on these rulings you could cut any crystal down the centre and have only half a crystal but still
be able to work out what the missing portion would contain.

I will have to think on this some more it is just within reach to fathom out why 8 I Ching Hexagrams do not conform to go on to make 4 whole Hexagrams.
