Information
Proposer(s): Gilles Roux
Proposed: 2003
Alt Names: LSE, L6E
Variants: ELL, L5E
Subgroup:
No. Algs: unknown
Avg Moves:
Purpose(s):
Previous state: 6Edges missing UM cube state
Next state: Solved cube state

6Edges missing UM cube state -> Last Six Edges step -> Solved cube state


The Last Six Edges step is the step between the 6Edges missing UM cube state and the Solved cube state.

Last Six Edges (abbreviated LSE or L6E) is a possible last step in 3x3 speedsolving that solves the M-slice centers and edges (UF, UB, DF, DB) together with UL and UR edges. It is the last step of the Roux Method and the Ortega Method.

Possible approaches

LSE can be solved in various ways; Gilles Roux himself, the inventer of the Roux Method, advocates a flexible/semi-intuitive approach to LSE without a strict division into substeps. The optimal approach is likely a combination of the approaches below.

Layers-based approach

  • 1. centers, BD, and FD
  • 2. ELL

This layer-based approach seems out of place in any method ending with LSE.

Original Roux

  • 1. Orient centers and edges
  • 2. Permute UR and UL edges
  • 3. Permute the M slice

The following two approaches are commonly used in Corners first methods.

Corners First approach 1

  • 1. Solve UL or UR
  • 2. Insert UL/UR while orienting the M slice
  • 3. Permute the M slice

Corners First approach 2

  • 1. Solve both UL and UR
  • 2. Orient and permute the M slice

Reduction to L5E has been proposed as an experimental approach.

L5E

  • 1. Centers and BD
  • 2. L5E
