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