CxLL
Corners Last Layer is a group of methods collectively known as C*LL or CxLL that solve the last layer corners in one algorithm. Each method has certain restrictions that apply, and each can affect other pieces in different ways. For example, CMLL allows movement of the M layer and allows destruction of the UL and UR edges. Two other common sets of algorithms include CLL and COLL. These differ from the fact that the latter preserves last layer's edges orientation while the former does not necessarily. In some cases, CLL will give shorter algorithms due to lack of restrictions.
C*LL is useful for the 2x2x2, which has no edges, and also for corners first, which solves edges after the corners. C*LL is also used in Roux's method, and is specifically known as CMLL.

At bottom of each page there is a navigator that you use to browse from page to page by clicking the names under the thumbnail images.
Case Descriptions
There are 2 tables for case descriptions. The first is the positional recognition system and the second is the hyperorientation recognition system.
Positional System:
Hyperorientation System:
| valign="top"| All color patterns show the orientation case in white. The blue and green stickers show the position of opposite color stickers (red/orange, blue/green, white/yellow on the standard scheme).
In case descriptions there are sometimes links to the "inverse case", that is the case you get if you do N-PLL on the case you got (or faster R2 F2 R2).
The Algorithms
At each page there are list of algs for diffrent types of CxLL menthods, topmost is COLL followed by CLL, CMLL and so on. An alg suitable for COLL is always also suitable for CLL but a CLL is newer useful for COLL, if your CLL preserves LL edge orientation then it is a COLL and should be listed as that. If your alg destroys M slice edges then it is a CMLL, if it ruins F2L edges it is a CF / 2x2x2 and if it changes FL corner premutation it is a EG 0/1 alg (all levles are also useful for Ortega). CLLEF differs from COLL only that it flips the orientation of all four LL edges.
Beginners
For a beginner who likes a stepping stone it is possible to do CxLL in two steps; first orientation and then permutation. In the navigator these algs are the grey cases having single letter names, orientations are in the leftmost row and permutations in the topmost line.
