4 look last layer

So far to my understanding the more algs u memorize, less moves to solve the last layer. 4 look last layer is a begginers move? To do accomplish a 2 look last layer would you have to memorize massive amounts of algs? i think so....

4 Look :
Orient Edges (2)
Orient Corners (1)
Permutate Corners (1)
Permutate Edges (3)

3 Look :
Orient Edges (2)
Orient Corners (1)
Permutate Edges and Corners (21)

2 Look :
Orient Edges and Corners (57)
Permutate Edges and Corners (21)

Numbers in brackets are the least number of algorithms you need to learn. And I think that's right, correct me if I'm wrong.

I have posted this in earlier topics, but I hope this will be a good summary:



For a true beginners method, all you need is 4 algs, but you might have to repeat some of them up to 3 times

Edge OLL (step 1):
1-3, 2 edges, horizontal) F R U R' U' F'

Corners OLL (step 2):
2-1, 1 corner, sune) R U R' U R U2 R'

Corners PLL (step 3):
3-1, 3-cycle) R' F R' B2 R F' R' B2 R2

Edges PLL (step 4):
4-1, 3 cycle left) F2 U L R' F2 L' R U F2

Worst-case could mean 3+3+2+3=11 look.



For a little more advanced method, all you need is the previous 4 + 3 extra = 7 algs, but you might have to repeat some of them up to 2 times
All 3 extra algs are just the inverse of the alg you already know for that step


Edge OLL (step 1):
1-2, 2 edges, diagonal) F U R U' R' F'
1-3, 2 edges, horizontal) F R U R' U' F'

Corners OLL (step 2):
2-1, 1 corner, sune) R U R' U R U2 R'
2-2, 1 corner, anti-sune) R U2 R' U' R U' R'

Corners PLL (step 3):
3-1, 3-cycle) R' F R' B2 R F' R' B2 R2

Edges PLL (step 4):
4-1, 3 cycle left) F2 U L R' F2 L' R U F2
4-2, 3 cycle right) F2 U' L R' F2 L' R U' F2

Worst-case could mean 2+2+2+2=8 look.



For a complete 4 look, all you need is the previous 7 + 9 extra = 16 algs, so you never have to repeat any of them

Edge OLL (step 1):
1-1, 0 edges) L' l U l' U2 l U L' U l' L2
1-2, 2 edges, diagonal) F U R U' R' F'
1-3, 2 edges, horizontal) F R U R' U' F'

Corners OLL (step 2):
2-1, 1 corner, sune) R U R' U R U2 R'
2-2, 1 corner, anti-sune) R U2 R' U' R U' R'
2-3, 0 corners, extended sune/racecar) R U R' U R U' R' U R U2 R'
2-4, 0 corners, T) R U2 R2 U' R2 U' R2 U2 R
2-5, 2 corners, Front) R' F' L F R F' L' F
2-6, 2 corners, Left) R' F' L' F R F' L F
2-7, 2 corners, Back) R2 D' R U2 R' D R U2 R

Corners PLL (step 3):
3-1, 3-cycle) R' F R' B2 R F' R' B2 R2
3-2, diagonal swap/small r) L' U' L F2 R' D R U R2 D' R2 U' F2

Edges PLL (step 4):
4-1, 3 cycle left) F2 U L R' F2 L' R U F2
4-2, 3 cycle right) F2 U' L R' F2 L' R U' F2
4-3, 4 cycle straight/cross) r2 R2 U' r2 R2 U2 r2 R2 U' r2 R2
4-4, 4 cycle diagonal/z) R' U' R U' R U R U' R' U R U R2 U' R' U2

Worst-case could mean 1+1+1+1=4 look.



Next step would be to learn how to combine step 3 and 4 to do full PLL. For that you would need to learn the 6 PLL algs + 15 extra PLL algs = 21 PLL algs. Combined with 3+7 OLL algs = 31 algs for a 3 look



Final step would be to learn how to combine step 1 and 2 to do full OLL. For that you would need to learn the 10 PLL algs + 47 extra OLL algs = 57 OLL algs. Combined with 21 PLL algs = 78 algs for a 2 look



After that come the expert methods like ZB or VH

You forgot that there are two 3-cycles
You only need to know the 2 algs I listed. Try this for yourself:
(I am assuming white bottom, yellow top, green/blue opposite, orange/yellow opposite)
If you have 4 faces with opposite colors on the top-corners, do 3-2
If you have 1 face with opposite colors on the top-corners, rotate the cube so that face is in the front and then do 3-1
If you have 0 faces with opposite colors on the top-corners, you have a skip.

If you still don't believe you only need those 2 algs for 4 look, please give me an example that sets it up. I am really sure about this, because I only know those 2 algs.

Might as well learn both cycles, though, because they're very similar algs, and it lets you get a skip EOLL rather than H perm some of the time.

I agree that it is useful to learn both cycles, but it would be even more useful to learn all 21 PLL's. The summary was about what you MUST learn. It isn't a good idea to complicate a summary like Cubinator did. I especially didn't like the he made it sound like you HAVE to learn 2 different 3 cycles.
Fair enough. It's just that the other cycle is just an inverse, so it's not like memorizing an entirely different PLL.

I am guessing you mean 1-1?
Edge OLL (step 1):
1-1, 0 edges) L' l U l' U2 l U L' U l' L2
1-2, 2 edges, diagonal) F U R U' R' F'
1-3, 2 edges, horizontal) F R U R' U' F'
small letters mean "that layer and the middle layer that is attached to it". small letter turns are sometimes referred to as wide-turns or thick-turns.

1-1 is basically a Sune + 4 edge-flip

Confused

I'm a newbie and don't understand what is meant by the items in blue below mean. Any help would be appreciated.

Edge OLL (step 1):
1-3, 2 edges, horizontal) F R U R' U' F'

Corners OLL (step 2):
2-1, 1 corner, sune) R U R' U R U2 R'

Corners PLL (step 3):
3-1, 3-cycle) R' F R' B2 R F' R' B2 R2

Edges PLL (step 4):
4-1, 3 cycle left) F2 U L R' F2 L' R U F2
The first parts, "1-3", "2-1", "3-1", and "4-1" are just names that the poster applied to each case; you can ignore these.

"2 edges" and "1 corner" for the OLLs describe how many of the pieces will already be oriented.
So for the edges OLL case, there need to be 2 edges solved. Those edges need to be horizontal, as opposed to adjacent.
For the corners OLL case, there needs to be 1 corner solved. "sune" is just a name given to that algorithm.
For corners PLL, "3-cycle" means that three corners will cycle around the cube.
For edges PLL, the same thing. "Left" is a bit unclear. What it should say is "clockwise", which is the direction the edges cycle in.
