+ | '''First Two Layers''', or '''F2L''' refers to the first two bottom layers of the [[3x3x3 cube]], or essentially all layers up until the last layer on larger cubes. | ||
+ | |||
+ | The definition is a little different depending on the subject or who you are talking to. Usually, it refers to the part of the [[CFOP]] and [[CFCE]] methods that solve the first two layers in [[pair]]s, excluding the [[cross]] step. Or it can refer to [[ZZ]]'s F2L. | ||
− | + | [[2-gen]] F2L, most pairs (30 of 41) have the edge sitting in the U-layer having two orientations, it shows R or F colour at the side. If it is the R colour you can solve the pair using only RU and if it is the F colour you can turn the cube (y') and solve the pair to the back slot using only R and U moves. The only pairs that needs both R and F turns are the six ones with the edge unoriented in the slot, if the edge is oriented in the slot both ways works. | |

− | The concept of pairing up four corner/edge pairs was first proposed by [[ | + | There are many ways to solve the 'F2L' on a cube. A common system is using the [[Fridrich]] method first two layer approach. After solving the cross, a corner-edge pair is paired up ('''form pair'''), and then inserted into the correct slot ('''pair insertion'''). A total of four corner edge (or 'CE') pairs are made and inserted to solve the first two layers. This step of the cube should be done intuitively, even though there are algorithms for each case, algorithms should only be used for slower cases. |
+ | |||
+ | The concept of pairing up four corner/edge pairs was first proposed in 1979 by [[John Conway]], [[David Benson]], and [[David Seal]] in two separate publications.[https://sites.google.com/view/methodlibrary/3x3-methods/cfop] The idea appeared in other publications starting in 1981. | ||
+ | |||
+ | === ZZ F2L === | ||
+ | ZZ F2L is very similar to CFOP F2L, but there are some differences in ways you can pair up pieces. ZZ is more blockbuilding centered, and in result, F2L can be completed using block building. | ||

First Two Layers, or F2L refers to the first two bottom layers of the 3x3x3 cube, or essentially all layers up until the last layer on larger cubes.
The definition is a little different depending on the subject or who you are talking to. Usually, it refers to the part of the CFOP and CFCE methods that solve the first two layers in pairs, excluding the cross step. Or it can refer to ZZ's F2L.
2-gen F2L, most pairs (30 of 41) have the edge sitting in the U-layer having two orientations, it shows R or F colour at the side. If it is the R colour you can solve the pair using only RU and if it is the F colour you can turn the cube (y') and solve the pair to the back slot using only R and U moves. The only pairs that needs both R and F turns are the six ones with the edge unoriented in the slot, if the edge is oriented in the slot both ways works.
Approaches
Petrus F2L
Another way to solve the 'F2L' is by building blocks, common during the first two layers of the Petrus method.
Fridrich F2L
There are many ways to solve the 'F2L' on a cube. A common system is using the Fridrich method first two layer approach. After solving the cross, a corner-edge pair is paired up (form pair), and then inserted into the correct slot (pair insertion). A total of four corner edge (or 'CE') pairs are made and inserted to solve the first two layers. This step of the cube should be done intuitively, even though there are algorithms for each case, algorithms should only be used for slower cases.
The concept of pairing up four corner/edge pairs was first proposed in 1979 by John Conway, David Benson, and David Seal in two separate publications.[1] The idea appeared in other publications starting in 1981.
ZZ F2L
ZZ F2L is very similar to CFOP F2L, but there are some differences in ways you can pair up pieces. ZZ is more blockbuilding centered, and in result, F2L can be completed using block building.
