Z permutation algorithm
PLL (permute the last layer). Group: Edges only.
Z permutation: the top face is yellow all over. The algorithm swaps the front edge and the right edge, and swaps the left edge and the back edge.
The diagram shows the cube from above with the front at the bottom and yellow on top.
