A polyhedral shape interlocking puzzle designed and made by Junichi Yananose in 2016.
The shape of the puzzle is based on a compound of cube and octahedron.
The inner octahedron itself is not self-standing. Once the outer cube is assembled containing the inner octahedron, the entire burr puzzle becomes stable and self-standing.
10 types of the pieces are used for both to the cube and octahedron to make the puzzle tricky and difficult enough even to serious puzzle enthusiasts.
The color of Jarrah timber of this puzzle is rather orange or light brown than red.
The puzzle is named after Prof. Reza Sarhangi who made great contributions to math-art community.
