As you know, 'image variation' on ADOBE Photoshop is easy color manipulation system.
The center is origin(now), and six color variations are around it. If any color variation are selected, this will be center=next origin(now). If GMP accept the system like this, the new concept is below.
The eight simple operations are around the origin (Of cource, this is conceptual figure).
The center is simple object at first. Next, apply each operation for copied object. I'll get eight new shapes. Select no.'2' shape, this will be next original shape.
Next, apply each operation again. I'll get another new shape. The operation number that I selected is 'Gene' data. [2, 6, 5, 5, 8, 7, 1...]
So, I could trace the line of operations perfectly by this numbers.
This is next concept of GMP.
