The following is an example of a case for which no misplaced facelets can be fixed, it is the only case of this type that will occur while solving a random cube (case means this configuration and all those that can be made by doing half-twists to it or rotating the cube). This case is distinguished as having six misplaced facelets with two per slice and one per cubie. While there are several different possible configurations for this case, Sequence 3C-E3 applied to any two misplaced facelets will relocate them so that the cube can then be solved. Note that after applying the sequence there are two more misplaced facelets than before, that is avoided with the alternate method shown on the second cube below but three sequences are needed to solve either way.
