Ab perm is easy to identify and easy to learn. It is just one of the 21 different algs you should learn when learning full PLL on rubik’s cube. The PLL algorithms are used for the top layer, when the rest of the cube is solved. They are the final algs you need to do to solve a rubik’s cube.
In this guide we will cover everything you need to know about the Ab perm. From what it looks like, how to get it on your cube, and what you can do to solve it.
The algorithms here will be shown using rubik’s cube notation. If you need help with learning rubik’s cube notation please see our guide on cube nation before moving onto this stage.
What Ab Perm Looks Like
A perms are identified by looking at the corners of the top layer of the cube. You will see that the edges are all solved but only one corner is solved. There are still three corners that need to be fixed.
The Ab perm is used when the incorrect corners can be solved by moving them in an anticlockwise direction around the cube. If they need to be moved in a clockwise direction it means you need to do an Aa perm instead of an Ab perm.
How to Get a Rubik’s Cube into Ab Perm Position
To get your cube into the same position shown above, begin by holding the cube so the blue side is on the front facing you. The yellow side should be on the top, which will make the left side orange and the right side red.
From here, perform the following algorithm
l’ U R’ D2 R U’ R’ D2 R l
This alg is in fact one of the algorithms used to solve the Aa perm. You can do this and then use on of the following algorithms to solve the Ab perm.
How to Solve Ab Perm
There are a few different algorithms you can use to solve the Ab perm. Begin by holding the cube in the correct position. Take a look at the picture above. As you can see, on the bottom left side of the cube you have a solved corner, with two solved edges. You also have what is known as headlights on the right side of the cube.
Make sure the top layer is orientated like this and then choose one of the following algorithms to solve the Ab perm:
1: l’ R’ D2 R U R’ D2 R U’ L
2: x R2 D2 R U R’ D2 R U’ R
3: y U’ R’ F’ R U R U’ R2 F R U R’ F’ R F
4: y l U’ R D2 R’ U R D2 R2
