Step 3
|
Edges in 'edge' position When all the edges have been processed, your cube will look like this:
In the general case: the edges are in the 'edge' position the centers are in the 'center' position
In our particular case: LD, BL and RU are not oriented at 0° or 180°
|
Exchange of U and RU Seen from the Up side
for the presentation
Seen from the Front side
for movements
W = (R4 U R4 U')3
FU->BD permutation
|
|
Step 4
|
The global parity of edges When all the edges have been processed, your cube will look like this:
In the general case: there is only an even number of edges which are oriented at 0° or 180°
In our particular case: BU and FD are not oriented at 0° or 180°
|
90° rotation of LD, BL and RU Seen from the Left and Up sides
for the presentation
Seen from the Front and Right sides
for movements
W = (R4 U R4 U')3
|
|
Step 5
|
Individual parity of edges When all the edges have been processed, your cube will look like this:
In the general case: all edges are oriented at 0° or 180°
|
90° rotation of BU and FD Seen from the Up and Front sides
Warning: this algorithm will not be able to resolve certain situations, it will therefore be necessary to perform the algorithms of step 6 beforehand in order to place the edges on the same layer.
W = (R4 U R4 U')3
|
|
Step 6
|
Placement of edges When all the edges have been processed, your cube will look like this:
In the general case: all edges are well placed
In our particular case: FU and BD are oriented at 180°
|
Exchange of BL and FR Seen from the Left and Front sides
W = (R4 U R4 U')3
|
Exchange of FL and FR Seen from the Front side
W = (R4 U R4 U')3
|
Exchange of BL and FU Seen from the Left and Front sides
XF = (R4 F' R4 F R4)
W = (R4 U R4 U')3
XF = (R4 F' R4 F R4)
|
Exchange of FU and BR Seen from the Front and Right sides
XF = (R4 F' R4 F R4)
W = (R4 U R4 U')3
XF = (R4 F' R4 F R4)
|
|
Step 7
|
The placement of the centers When all the centers have been processed, your cube will look like this:
In the general case: all the centers are well placed
In our particular case: the edges FU and BD are oriented at 180°
|
L->F->R permutation Seen from the Front side
W = (R4 U R4 U')3
|
|
Step 8
|
The definitive orientation of the edges When all the edges have been processed, your cube will look like this:
In the general case: all edges are well oriented (0°)
|
180° orientation of FU and BD Seen from the Front and Down sides
for the presentation
Seen from the Up and Front sides
for movements
W = (R4 U R4 U')3
|
180° orientation of FU and FD Seen from the Front side
W = (R4 U R4 U')3
|
180° orientation of LD Seen from Left and Down faces
for the presentation
Seen from the Left and Front sides
for movements
W = (R4 U R4 U')3
