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