A Basic 5-Step Solution of Rubik's Cube
Alternate Middle Layer (Step 3):
We could use the 3-cycle from step 5 when we solved the middle layer in step 3. See the video for how to do it.
Placing Middle Layer Edges (alternate)
Alternate Edge 3-cycle (Step 5):
Here is another edge 3-cycle which is similar to the 3-cycle we used for the corners.
