I have a small observation. Shouldn't the diagonal(E) translation at the
central rosette involve all the cells of similar color which touch
edgewise on the level? This would correspond to the triagonal(C)
translations to the next level. Which are indentical in a cubic field.
The only restriction that I would give to diagonal(E) movement is that a
piece must translate through opposing edges of the cell when crossing it.
