Conditional Zeros with no rotation effect Conditional Zeros with a rotation effect Fractional Zeros 1. I.e. if we have a box with the heads on the outside where everybody is facing their corners, after the zero it is a box again with the heads on the outside, everybody facing their corners. It maintains the sequence It maintains relationship from any given sequence. That means from any box you have the true zero returns the dancers to the same box, the same dancers on the outside as before, everybody facing the same dancer as before. The formation itself might be in another geographical position, that does not matter.
Geographical zeros are a special kind of true zeros and they have the same properties.
I.e. if we have a box with the heads on the outside where everybody is facing their corners, after the zero it is a box with the sides on the outside, everybody facing their corners. Everybody is facing their corners. We have a Zero Box again, everybody is facing their corners, everybody is in the right sequence for an Allemande left. But this time the sides are in the center of that box. In the above example the conditional zero converted the Heads Square Thru Box in a Sides Square Thru Box.
