There are only 6 regular polytopes in 4D.

```
* The 5-cell corresponding to the tetrahedron in 3D<br>
* The 8-cell corresponding to the cube in 3D<br>
* The 16-cell corresponding to the octahedron in 3D<br>
* The 24-cell corresponding to nothing in 3D<br>
* The 120-cell corresponding to the dodecahedron in 3D<br>
* The 600-cell corresponding to the icosahedron in 3D
```

Which of these are offered as sliced playable programs?

I know 5-cell, 8-cell and 120-cell.
