Corner placement When the corners are placed, your Pyramorphix might look like this:
|
|
|
|
There are in fact 27 scenarios (3*3*3) but only 3 are represented.
You must first choose a reference corner.
Then only the movements L2' (case 1) or R2 (case 2) will put this corner in its place.
Cases where the corners are correctly oriented are not shown.
The last case is the one where the 2 remaining pieces are not in their place, in this case (case 3), it is movement D2.
There are in fact 9 scenarios (3*3) but only 2 are represented.
|
|
Choice of reference corner Just look at the colors on the left and right sides of the reference corner (here: yellow and red).
The corner you are looking for is the only other one that also has these two colors, the third color will be blue (the one below).
|
Case 1a The corner to be placed behind is on the left
The corner is turned +120°
|
Case 1b The corner to be placed behind is on the left
The corner is turned -120°
|
Case 2a The corner to be placed behind is on the right.
The corner is turned +120°
|
Case 2b The corner to be placed behind is on the right.
The corner is turned -120°
|
Case 3a The 2 corners on the left and right must be exchanged.
Corners are turned +120°
|
Case 3b The 2 corners on the left and right must be exchanged.
Corners are rotated -120°
|
|
Step 3
|
The placement of the centers When the centers are placed, your Pyramorphix will look like this:
|
|
The corners are represented with the same color on all faces, because they are not yet oriented, this shows that they are not moving.
The choice of their color was based on the only color they cannot have.
|
|
Case 1 Identify the color that does not appear on the reference corner. Find the center of this color, this center should be placed opposite the reference corner.
If it is not in its place, then:
|
Case 2 There are only three centers left that are not yet resolved, namely those adjacent to the reference corner.
If it is necessary to perform a circular permutation clockwise, then:
|
Case 3 There are only three centers left that are not yet resolved, namely those adjacent to the reference corner
If it is necessary to perform a circular permutation counterclockwise, then:
|
Case 4 If only two centers are incorrect, they must be swapped:
|
|
Step 4
|
The orientation of the corners When the corners are oriented, your Pyramorphix will look like this:
|
|
|
|
|
Case 1
To rotate the corner clockwise, perform the following action:
|
Case 2
To rotate the corner counterclockwise, perform the following action:
|
|
Your Pyramorphix is resolved.
