Does anyone know a proof for the fact that on a 3x3x3 cube always an even number of edges are flipped?[Defining flipped as the edges cannot be put to their right position in the right orientation with the <U,D,F2,B2,R,L> subgroup]
Also is there a proof for the fact that if a cw rotation of a corner is put as 1 and a ccw rotation is put as 2 and a correct orientation as 0. Then the summation of the numbers after any moves made on the 3x3x3 is always divisible by 3?
