Step 4: Permute the corners within their layer (8 algos)


For beginners, use algo 5 to fix top layer (max 2 times) and algo 8 to fix bottom layer (max 2 times), see beginner: step 4 and beginner: step 5 for more explanations.
Two corners have to be diagonally exchanged if there is not 2 adjacent corners with the same side color.
