Important Issues and Notes
The algorithm provided for step 3 should be enough, even though it isn't a three-cycle.

Useful Algorithms
In step 3, swap two pairs of edge faces: (fr ur fr ur) UF (fr ur fr ur) UF
In step 4, three cycle centers: (fr UF fl UF) x 2
In step 4, four cycle centers: (uf fr ur) x 3
In step 5, three cycle corner centers: (FR UF FL UF) x 2
