2.Edges_Goal 4: Displacing / Placing Side Edges

Your White and Yellow Corners and Edges are all correct, and your White side is face down, Yellow is up.

Now we are looking at the Edges on the Sides of your Cube. This step will place them. If there are Edges on the Side of the Cube that are not correctly placed, we will temporarily displace two of the Yellow Edges, in order to reposition the incorrect side Edges up to the top-back of the Cube Where they can be placed.

Roughly half the time, when the Yellow Edge Pieces make their way back to the Top, they will be correctly placed, but the rest of the time they will be in each other's space. When this happens, it will be resolved in the next step. This step only concerns itself with the correct placement of the side edge pieces (which do not have White or Yellow).

Formula B for Edges places an Edge piece from the top-front to the front-left side.

DEMONSTRATION:

SETUP 1:

If there are any incorrect Side Edges, hold the Cube so that, with the White side still down, there is an incorrect Edge piece on the left-front edge of the Cube.

PLACEMENT 1:

Use Formula B to place a Yellow Edge into the space where the incorrect Edge is on the Left Side.

SETUP 2:

Now Rotate the Cube front-to-back so that the Edge piece you just displaced is in front where you can look at it. From this point forward, we are ignoring every other piece on the Top, specifically, we are only looking for the one Edge piece on the top that DOES NOT have Yellow on it. This is your Active Edge.

NOTE: Up until now, we have been keeping the Corners correct to each other, but we are now ignoring the Yellow Corners, and we will be moving the Top layer independent of the rest of the Cube. We are focusing primarily on the White (Bottom) Corners, and matching Edge pieces to the other colors on the Corners.

The Edge piece on the top that does not have Yellow, has two side edge colors. With that piece on the top-front side, keeping the Top Row stable, Twist the rest of the cube until the color on the front of the Active Edge piece match the front color of the bottom Corners.

PLACEMENT 2:

If the Left Color is on Top, do Formula B to place the piece.

If the Right Color is on top, do the Mirror of Formula B as follows.

RESET:

One Again, look for the one Edge piece on the top row that doesn't have Yellow on it, and that is your new Active Edge. Return to SETUP 2 of rotating the cube until the Active piece matches the front color.

Continue placing Edge pieces at needed until the Yellow Edge that was initially displaced is once again on the Top, meaning all the Yellows are back onto the top.

At this time, either the Yellow Row is correct, or there are two Edges opposite each other which are misplaced, each Edge belongs in the other's place. This will happen roughly half of the solves, and is easily undone in the next step.
