image If we take || R.dot(p(k))-R.dot(p(k')) ||, it is equal to 1. Need some more explaination?

Yeah, the calculated distances after rotation are wrong though I can't remember how I made a mistake lol. This should have been pointed out ages ago; L1 is invariant to rotations of multiples of $90^{\circ}$. Thanks for this!
