Well, if you believe proof by example on a simulated puzzle, then
Tetrahedron period 2 turning: never happens
Tetrahedron period 3 turning: starts when n=4 with center triangle
Octahedron period 3 turning: starts when n=4 with center triangle
Octahedron period 4 turning: starts with n=4 with center triangle

New versions of my pyraminx and octahedron puzzles will be out soon
to reflect this.

```Cheers,
