Suggestions for learning 3-look LL?

[thelegend]

Does anyone have any tips for learning this? From the look of it, gota learn 21 PLL algs before you can actually practice with it. Is this what you guys did?

Your alternative is learning 5 PLLs and 57 OLLs.

But yeah, learn 3-4 per day, reviewing whenever possible, and you can learn them all in about a week.

For a 3LLL, you will need to learn quite a few. For 4LLL, you can survive with 17 algs. I copied this list from a post awhile back:
Orient Edges(the cross):

Cases 1 and 2
http://www.geocities.com/rubiks_galaxia/OLL5.html
the first case on there...

Orient Corners-- use 4, 6, 7 and 9 from this page...

Case 52, 50(the one that is (R U R' U R U' R' U R)(U2 R'))

Case 3

Case 5 the first algorithm that begins with the x...

I think thats all...those 17 will get a 4LLL all the time...

The way I learned it is probably a lot slower than most other people. Starting with PLL, I learned about 3 PLL's in a week. Of course, this was to make sure I had a good grasp on it. Though, by the last week, I got impatient, so I started to rush through the G-perms and the N-perms. After that, I learned the rest of the OLL algs I needed for 3-look LL, which was only a handful, in a couple of days.

So my suggestion to you is to learn PLL first, taking as much time as you are willing to spend on learning them. Learning them faster or slower than how I learned them is entirely up to you. After you have the PLLs, you can move onto the OLLs needed for 3-look LL.

PJK, you don't need 17, but 16 (3+7+2+4) algs for a full 4 look last layer:

Edges OLL: 0 Oriented correctly = 1
Edges OLL: 2 Oriented correctly = 2 (adjacent, opposite)

Corners OLL: 0 Oriented correctly = 2
Corners OLL: 1 Oriented correctly = 2
Corners OLL: 2 Oriented correctly = 3
(http://www.deepcube.net/intermediate.html#orientcorners)

Corners PLL: 2 Permutated correctly = 2 (adjacent, opposite)

Edges PLL: 0 Permutated correctly = 2 (adjacent (z), opposite (+))
Edges PLL: 1 Permutated correctly = 2 (3-cycle left, 3-cycle right)

TheLegend: You should group all PLL's in cases that are alike. For example mirrors/inversions or "Corners correct, corners opposite, corners adjacent". Then learn that entire group at once.

Alright thanks guys, I'm going to gradually learn PLL. So far, I know corners correct and a few others. One other thing, is it ok that I learn 3-look without first learning 4-look? I average one minute using the backend of petrus after F2L.

 

[AvGalen]

Learning 3-look without knowing 4-look would be difficult. You would often get cases that you don't know how to do in 1 look or in 2 looks, so the solve would be unsuccesful or at least very weird.

If you already know corners correct (step 4, edges PLL = 4 algs)) then you only need to learn 2 Corners PLL algs to learn the 4 look last layer.

(I am assuming you can do OLL 2 look)

My first bit of advice on learning the 21 PLL's is to not be intimidated by it. I remember when I first decided to learn those algorithms, I felt that there was no way that I would ever be able to recognize the cases when they came up. If you keep at it, you will start to develop your own way of recognition and it gets easier.

My next bit of advice is to learn the algorithms in a certain order. you start with the more common algs, and work your way up to the others. Start by performing the algorithm over and over until it is stored in your muscle memory, and then actually watch the cube as you perform the alg and you can generally pick up patterns that the cube makes. Kind of like a map to follow over the course of the algorithm.

I hope this helps,

Frank

Ok thanks guys, the 4LLL sounds like a good idea since I already know most of it, just several more OLLs to use it effectively. PLL memorizing isn't so bad once you get going, but I'll really start grinding them out in a week or so after I'm good on the two look OLL. Thanks again.
