Uniqueness of the 120-point spherical 11-design in four dimensions

We prove that on the Euclidean sphere S3 there exist a unique up to isometry 120-point spherical 11-design and a maximal (4, 120, \( cos(\pi/5) \))-code. Both these are nothing but copies of a famous regular polytope in four dimensions – the 600-cell.
