'''1LLLL''', an abbreviation for '''1'''-'''L'''ook '''L'''ine '''L'''ast '''L'''ayer, is a [[subset]] to meant for solving the [[last layer]] (1 look) in 17 algorithms.

== About ==
In order to bring the number of cases for the last layer down to 18, (including the solved case) some [[F2L]] influence is needed. [[Edge orientation]] needs to be solved before [[F2L-1]], so that the last layer algorithm count goes to 493 ([[ZBLL]]). After that, the last [[F2L pair]] is solved along with 3 adjacent last layer pieces (2 [[corners]], 1 [[edge]]). This will bring the amount of cases down to 18(including the solved case), 5 of which are [[PLL]]s.

This subset can be used for [[CFOP]] when EO is skipped(which can be recognized easily), similar to [[Winter Variation]], while [[ZZ]] and [[Petrus]] can use this in every solve

== Steps ==
# '''F2L-1 + EO:''' Solve EO, and then F2L-1.
# '''U Pair:''' Make a corner-edge pair of U-layer pieces and place it in the [[F2L]] slot
# '''Last Slot:''' Connect the final [[F2L pair]] without disturbing the pair in the slot. Then use one of nine algorithms to solve the F2L pair while setting up the Line Last Layer
# '''1LLLL:''' Solve the [[Last Layer]] in one look by using one of seventeen algorithms
