@HG: somewhat it gives me some explanation, somewhat I'm more confused than before. So, HG, taking this "The meaning of z in a multi-leg move has also changed; it now means l or r, but the opposit of what the previous leg did. (So that it can be used to specify crooked paths)"; how would you write that Betza's Rhino and Mirror-Rhino?
@Haru N Y: your notations do work but I can't understand why. Indeed I belong to those not digesting the "a" at all. And why do you call the Mirror-Rhino a Snake? That confuses me even more too.
