Purpose(s):

CLL, Corners of Last Layer, a step that solves the last layer corners in one algorithm.

CLL is not to be confused with COLL that is an abbrevation for exactly the same name but COLL does also preserve LL edge orientation, sometimes you will need longer algorithms for that.

There are two different sets of CLL, one that is used for corners first (the Waterman method) and the 2x2x2 cube and one that preserves the first two layers on the 3x3x3 cube. In the latter case the LL edges are solved after the CLL using ELL.

As a 2x2x2 Speedsolving Method

The first stage of CLL for the 2x2x2 consists of completely solving one layer of the cube (both orientation and permutation) as in the Layer-By-Layer method. Then, using one of 42 algorithms (2 of which are PLLs), you solve the remaining orientation and permutation of the last layer (thus giving a 1 Look Last Layer). The algorithms needed are given in the CxLL pages. This method is also named the Waterman method after the 1980s master cuber Marc Waterman from the Netherlands who was using it for his corners first method back then (the Waterman documentation).


History

CLL was first officially used by Guus Razoux Schultz (WCA) during the WC 1982.
