Hi

Recently I asked the question:

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.
