Sheet Guide (Important)
EPLL is the last step of the Lin Method, in which you
solve the edges of the last layer (as the name suggests).
The set is made of 9 algorithms, 5 of which are parities.
To your discretion it is possible to only learn the
Adjacent Swap parity alg, and using it to reduce any of
the other parities to a non-parity case.
Despite this, I highly recommend you learn all of them,
considering the time that this is going to make you gain.
You can find all the fingertricks in the Other Sources section.
