However, below are two algorithms you need to solve these 4 edges.

z 3R2 U2 3R2 U2 z' (adjacent 2 2-cycle)

z F2 3R2 U2 3R2 U2 F2 z' (diagonal 2 2-cycle)

In addition, you will need to solve three edges in the middle layer in some solves.

z 3R U2 3R' U2 z' (3-cycle)

z U2 3R U2 3R' z' (3-cycle) (the inverse of the first 3-cycle
