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