'''Edges of Last Layer''', or normally '''[[ELL]]''', is a [[method]] that solves the last layer [[edge]]s of the [[3x3x3]] in one algorithm as the last step in the solution, normally after performing [[CLL]] to solve the last layer [[corner]]s. There are 29 cases in ELL, of these are three pure flips, four are [[EPLL]] and six cases are 3-cycles (besides the two in EPLL), all useful also for other methods, like [[BLD]].

ELL is also used for a method of solving the last layer edges on larger cubes. Since there are 8 of each type of [[wing]], though, ELL for larger cubes requires more than one look due to the large number of cases, see [[KBCM Step 6|KBCM]] for a compleate 3-look ELL for the [[4x4x4 cube]].

Use any ELL that orients what you currently got (3 cases) from the listings below and finnish it using [[EPLL]] (4 cases). Most [[OLL]]s that preserves corner orientation will probably also do for the first look but don't count on it, some may change corner permutation while orienting the edges.

ELL method
ELL.png
Information about the method
Proposer(s): Guus Razoux Schultz
Proposed: 1981
Alt Names:
Variants: EOLL, EPLL, L5E
No. Steps: 1
No. Algs: 29
Avg Moves: ~11 STM (Speed-optimized) Optimal: 11.27 (HTM), 9.03 (STM)
Purpose(s):
This page is about the ELL that solves edges preserving corners, for the method that does not, see LL edges first

Edges of Last Layer, or normally ELL, is a method that solves the last layer edges of the 3x3x3 in one algorithm as the last step in the solution, normally after performing CLL to solve the last layer corners. There are 29 cases in ELL, of these are three pure flips, four are EPLL and six cases are 3-cycles (besides the two in EPLL), all useful also for other methods, like BLD.

ELL is also used for a method of solving the last layer edges on larger cubes. Since there are 8 of each type of wing, though, ELL for larger cubes requires more than one look due to the large number of cases, see KBCM for a compleate 3-look ELL for the 4x4x4 cube.

All ELL that are pure 3-cycles are used in the blindfold method TuRBo.

Intuitive

If you like to find algs for ELL in the MU-group, then knowing these short "proto algs" will help a lot:

  • O = M' U M ... Orient
  • O' = M' U' M ... Orient inverse
  • P = M' U2 M ... Permute

If you combine these and also insert U-turns you can find optimal or near optimal algs for most ELLs

Example, 4-flip: P U2 O U2 P U' ... P U2 sets up for O that flips four edges (O' works the same in this case, choose the fastets), U2 P is restoration of the setup and last U is AUF.

2-look ELL

Use any ELL that orients what you currently got (3 cases) from the listings below and finnish it using EPLL (4 cases). Most OLLs that preserves corner orientation will probably also do for the first look but don't count on it, some may change corner permutation while orienting the edges.

Another way to solve ELL in 2 looks is to use L5E, but that is desigend for solving one more edge than this is so there will be nearly the same number of algs as full ELL (5+16).

ELL Algorithms

Note that all of these algorithms are written in the Western notation, where a lowercase letter means a double-layer turn and rotations are denoted by x, y, and z. (how to add algorithms)

Click on an algorithm (not the camera icon) to watch an animation of it.

The naming convention here is; wich edges are fliped if they where permuted and which EPLL would it be if all was correctly oriented.
