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