Eight cases with two opposite edges flipped.
Goal
The first two layers and the four top corners are done. Two opposite edges are flipped, leaving a yellow line on top. One algorithm solves the cube.
How to recognize it
Words used here:
- : a top edge whose yellow sticker faces a side. Its color is the sticker facing up.
- : the edge has the color of the center of the side it sits on. A flipped edge can still be home.
- : the center on the far side of the cube (front and back, left and right).
Count the flipped edges and see where they are. Then find the edges that are home. If only one edge stays put, see which center's color the back or right edge has.
How to hold the cube
White on the bottom, with the top corners lined up with the centers. Every case is seen from this grip; the recognition text names positions as the cube starts.
The main idea
Cycle 2 uses the same algorithm as OLL 57 in , plus a one-handed version.
Final check
The whole cube is solved. Turn U once more if the top is still offset.
