DaYan Octahedron Vertex Turing Puzzle Transparent
This is a regular octahedron, of which each triangular face is divided into 9 identical smaller triangles, three to a side. A move consist of rotating a vertex; either just a tip (one triangle to a side) or a larger part (two triangles to a side). It is equivalent to a Rubik's cube puzzle without corners, but with the face centres marked to show their orientations. If you understand the solution for the Pyraminx, then you can probably solve much of this puzzle too, because it acts very similar.The number of positions:There are 6 vertex pieces with 4 orientations, 12 edge pieces with 2 orientations giving a maximum of 12!21264 positions.
