In this video I teach several commutators covering every piece type on the four layer face turning octahedron. These could come in handy if you make a mistake during the last layer of your solve. No need to start all over again with a reduction solve.

Inner edge piece three cycle.
Outer edge piece three cycle.
Off-center piece three cycle.
Corner piece three cycle.
Corner piece three cycle (permutation).
Center piece three cycle.
Center piece four swap.
Does the 4x4 FTO jumble?
