Step 1.1
|
The external edges and corners of the 1st layer When the outer edges and corners have been taken care of, your puzzle will look like this:
No particular algorithm.
The placement of pieces must remain intuitive.
|
Step 1.2
|
The central edges of the 1st layer When the central edges have been processed, your puzzle will look like this:
We will have to look for the central edges on the second layer and place them correctly in the manner shown opposite.
|
Case a The element to be placed is to the right on the 2nd layer
The algorithm allows you to lower it.
|
Case b The element to be placed is on the left on the 2nd layer
The algorithm allows you to lower it.
|
|
Step 1.3
|
The lateral edges of the 1st layer When the side edges have been processed, your puzzle will look like this:
We will have to look for the side edges on the 2nd layer or the 3rd layer and place them correctly in the manner indicated opposite.
|
Case a The element to be placed is to the right on the 2nd layer
The algorithm allows you to lower it.
|
Case b The element to be placed is on the left on the 2nd layer
The algorithm allows you to lower it.
|
Case c The element to be placed is to the right on the 3rd layer
The algorithm allows you to lower it.
|
Case of The element to be placed is on the left on the 3rd layer
The algorithm allows you to lower it.
|
|
Step 2.1
|
The central edges of the 2nd layer When the central edges have been processed, your puzzle will look like this:
We will have to look for the correctly oriented central edge on the second layer and place it at the back.
The other 2 central edges must be oriented in the manner indicated opposite.
|
The algorithm allows them to be swapped.
|
|
Step 2.2
|
The lateral edges of the 2nd layer When the side edges have been processed, your puzzle will look like this:
We will have to look for the side edges on the 3rd layer and place them correctly in the manner shown opposite.
|
The element to be placed is to the right
The algorithm allows it to go down to the left.
|
The element to be placed is on the left
The algorithm allows you to move it down to the right.
|
|
Step 3.1
|
The lateral edges of the 3rd layer When the side edges have been processed, your puzzle will look like this:
There is, a priori, no case where 2 lateral edges are permuted.
This case is therefore trivial.
|
Case a Rotate in direction clockwise
The algorithm allows them to be rotated.
|
Case a Rotate in direction counterclockwise
The algorithm allows them to be rotated.
|
|
Step 3.2
|
the external edge of the 3rd layer and the corner of the 4th layer When the outer edge and corner have been processed, your puzzle will look like this:
We will have to correctly place the side edges of the 3rd layer as shown opposite.
The corner of the 4th layer must also be placed correctly in relation to the outer edge of the 3rd layer.
|
Case a Rotate in direction clockwise
The algorithm allows them to be rotated.
|
Case b Rotate in direction counterclockwise
The algorithm allows them to be rotated.
|
|
Step 4
|
The centers When the centers have been processed, your puzzle will look like this:
Note: the blue side corresponds to the hidden side below.
|
Case a Only the 3 centers of the 2nd layer are poorly placed.
Rotate in direction clockwise
The algorithm allows them to be rotated.
It will then be necessary to reposition the elements of the third layer (case b)
The 4 centers will then be incorrectly placed, the Pyraminx 4x4 is then correctly oriented to apply the appropriate algorithm (case c)
|
Case b Only the 3 centers of the 2nd layer are poorly placed.
Rotate in direction counterclockwise
The algorithm allows them to be rotated.
It will then be necessary to reposition the elements of the third layer (case a)
The 4 centers will then be misplaced, the left face must first be brought back in front of you and you must then apply the appropriate algorithm (case c),
|
Case c the 4 centers are poorly placed.
Place the Pyraminx 4x4 so that the center underneath matches the face in front of you.
By convention, the blue side can be below but the side where the blue center is is not necessarily the green side.
