L6EP


L6EP or LSEP is a subset of LSE that permutes the last six edges, usually UF, UR, UB, UL, DF and DB, finishing the solve. Like LSE, it can be solved 2gen with only M and U moves. It is used in Corners First methods and Roux. For the latter, however, EOLR + 4c is more widespread than EO + L6EP.
A variation of it called "WaterZZ L6EP", where instead of the DB edge, the FR edge is permuted, is used in the WaterZZ method.
Possible approaches
Layersbased approach
 Solve the two D layer edges
 Finish the solve with EPLL
While this is easiest for solvers coming from CFOP, it is not very efficient.
Roux L6EP
 Permute UR and UL edges (Roux 4b)
 Permute the M slice (Roux 4c)
This approach is the most common as it is fully intuitive, very known due to the popularity of Roux and also pretty efficient.
One look L6EP
 Permute all six edges using one algorithm
While this is definitely the best approach in terms of ergonomics and movecount, it is rarely used due to the high amount of cases. However, since most cases are semiintuitive, learning can be done in a similar fashion to EOLR or intuitive F2L.
