L2L4 (Last 2 Layers, the 4th proposal) is a 3x3 speedsolving method invented by Duncan Dicks in the 1990s. L2Lk (Last 2 Layers, as proposed by Stachu Korick) is an alternate 3x3 speedsolving method developed in late 2010 through 2011.

History (outline)

  • Invention by Duncan Dicks (look up posts on Yahoo! group)
  • L2L1 to L2L4 proposed by Duncan, and after these initial thoughts, little to no development was done after the 1990s.
  • Recent developments, especially contributions of Stachu Korick.
  • L2Lk developed and published in 2010-2011

The Steps

-First, a 1x3x3 block is completed, typically on the D face, and called the "First Layer." -From this point, each of the LL-specific configurations of CO, CP, EO, and EP are completed, not necessarily separately or in that order.

Variants

L2L4

CO, CP, EO, EP

L2Lk

CO, CP, L2E, ELL

Pros

  • Once the first layer is done, little thought is needed. Processing and turning speed are both raised at this point.

Cons

  • High alg-count
  • First layer is difficult to optimize.
