The 600-cell is a 4-D regular polytope with 120 vertices whose facets are 600 tetrahedra and a special cut is a family S of vertices of 600-cells such that no two vertices in S are adjacent. The index n of this sequence is the number of vertices of S. Since the number of vertices in S is at most 24, the sequence is finite.
