Whenever my buffer is solved and I still need to pair up some edges, I don't insert a broken dedge in place of the buffer. I tend to just solve the rest of the edges in one go. If there are 4 dedges left, then I would solve 1 of the edges with a simple 3 edge cycle then solve the rest using one of the algs below.

2R' F R' F' R U' R U r​

x' R U' R2' F R 2U' R U R' F R' F' R 2U x
x' 2R2 D2 2R' U2 2R D2 2R' U2 2R' x​

2R U2 2R D 2R' U2 2R D' 2R2'
x' R' F R 2U' R U R' F R' F' R 2U U' x​

2R2 D 2R' U2 2R D' 2R' U2 2R'
(U2) x' R U' R' 2U' R U R' F R' F' R 2U x​

R U' R' U 2L' U R U' R' 2L
R U2 2R D 2R' U2 2R D' 2R' R'​

(U) B 3R' U' l' U' R U r
x' 2R2 D2 2R' U' 2R D2 2R' U 2R' x​

2L' R U R' U' 2L​

2R' U' R U r​

R U' R' U r U R U' 2R'
R 2R D 2R' U2 2R D' 2R' R'​

(U') 3R U 2R' R U R' U' 2R U' 3R'
x' 2R U' 2R D2 2R' U 2R D2 2R2' x
2R U 2R' F' 2R U 2R' U' 2R' F 2R2 U' 2R'​

2R U R' U' r'​

2L R' U' R U 2L'​



Enjoy.

If you're having trouble learning these algorithms, try doing some of the algorithms on a 333 using normal turns in place of wide turns e.g. x' Rw U' Rw D2 Rw' U Rw D2 Rw2' x becomes x' R U' R D2 R' U R D2 R2' x

@Faz: It's not too late to learn these ;)

No problem! Fortunately, these algs were very easy to find after a little bit of thinking. The hardest part was probably generating the images. You can click on the images to see how much I had to type in to get the desired LL image :p

These look pretty cool, but I doubt I'll learn them simply because I use E-slice pairing and I don't like the idea of doing z rotation-algorithm-z' rotation because it might mess up my flow.

x' Rw U' Rw D2 Rw' U Rw D2 Rw2' x

Can be replaced by

RwURw'U'Rw'FRw2U'Rw'U'RwURw'F' (modified T perm)

or

RwURw'F'RwURw'U'Rw'FRw2U'Rw' (modified J perm) (I use that one)

Bump...

I've added some more algorithms. The new algorithms are shorter and much easier to learn. I just experimented a little bit to find them. I'm sure you can easily understand how they work, so I wont explain, unless you want me to :p

Happy learning :)

Yep... What I do for the cases with 3 dedges is:

1. Rotate the top layer so that the solved edge is on the left.
2. Look at the UF dedge and locate their partners
3. Now you should be able to recognise which case you have.

When you have 4 dedges remaining that are like those in the very first figuration (one going horizontal and one going vertical, both in the top layer), you can solve it by doing a Y perm with Rw moves.

F Rw U' Rw' U' Rw U Rw' F' Rw U Rw' U' Rw' F Rw F'

I thought it was pretty useful and less awkward than doing the edge flip twice.

Can someone please upload the table as a PDF or something? For some reason my computer just doesn't want me to see the images. Thanks!
