When learning the fast method to solve the first two layers (f2l) of the Rubik’s cube, I started out with a list of all the beginning positions of the corner and edge piece and the algorithms needed to put them in position.  I saw that a lot of the algorithms were related.  Midway through one algorithm, I would find myself in the starting position of a different algorithm.  Or multiple algorithms would have the same ending.  I created a diagram to show how all the initial positions could move through the various permutations to get to the solved position so that I could see how they were all related and to help myself visualize the solutions.  In the hopes that my diagram might help others, I’m posting it here.
