This example (first cube) matches three of four facelets of the setup for Sequence 3C-E3 (second cube). Use the mouse to turn the first cube and see that there is a red misplaced facelet on the left face that should be yellow. Press Play on the first cube to see that the sequence fixes three misplaced facelets. The red misplaced facelet which did not match the setup will then be on the front face. The yellow misplaced facelet on the bottom face can be ignored.

This example (first cube) matches three of four facelets of the setup for Sequence 3C-E4 (second cube). Press Play to see that the sequence fixes three misplaced facelets. A yellow misplaced facelet will then remain on the top face. The red misplaced facelet on the back face can be ignored.

The next step is to look at what happens if only two of the four misplaced facelets can be matched.
