At the begging, I was using the following algorithms which are shorter. But they use a little awkward u/u’ turns and/or a cube rotation. So, I decided to change it.

R2 u R’ U R’ U’ R u’ R2 F’ U F

R’ U’ R y R2 u R’ U R U’ R u’ R2′

R2′ u’ R U’ R U R’ u R2 y R U’ R’

R U R’ y’ R2 u’ R U’ R’ U R’ u R2
