Rubik's Cube: Part 1: Representation
 Introduction: purpose, group theory, experiments, uncover behavior
 How does the Rubik's Cube work  pieces, colors, and faces

Rubik's Cube: Part 2: Permutations

Introduction: Study sequences and the permutations that result 
How do we represent a particular permutation? Start with ntuple representation from prior post 
Now, when we rotate a piece, we can map the pieces involved in the rotation 
Sequential application of transformations result in new tuple, unique to cube permutation
