Rubik and Cubic

After the lecture, I made a small animation of the 2 x 2 x 1 Rubik which is is the group S₃ which is also the Galois group of the cubic. The 2x2x1 Rubik group can also be seen as the dihedral group D₃ which are the symmetries of the triangle. It is generated by two reflections. The cubic is first depressed, then with a substitution rendered into a form u³ = k, where k satisfies a quadratic equation (Galois group S₂). Mathematicians say, the group S₃ is solvable.
