Step: a 2 3 4 5 6 7 8
Now position the four edges middle position. It does not have a direct right, its edges could be reversed, but the important is the right place. If the upside, we'll finish up later in the next step.
If all edges already in place right, just go to the next step.
Find edges are already in the correct position. See picture. Green-orange edges already in the right place.
Or search these edges are also allowed to
A. The formula for rotating the three edges at once
above formula will rotate between the three edges at once. See the picture below:
If you have a case "only has one middle edges are already in place", you can perform this rotation formula by placing the position of edges that have been in place back to you on the layer Under . See picture.
Edges
green-orange has been put in place in your back (behind the cube) in the layer below.
If you do not find the edges are already in place, then you will find that its edges-edges-entered for each other. To change the two edges of each layer and the two edges of the layer below, making this formula:
B. The formula to convert the two edges in the layer above and two edges in the layer below
Rmuus above will change the two edges in the layer above and two edges in the layer below.
See picture.
If completed, move to the middle of four edges in place, so if Rubik's Cube you have not already, let's go to the next step.
next step: Reversing the Reverse Edges
