Four of the six pieces have diagonal notches on both sides of the large, simple notch. Two pieces have them on only one side. Normally, a six-piece burr consisting only of pieces with a single, large, simple notch could not be assembled. With the diagonal notches described, it becomes a coordinate motion puzzle - a difficult one! Number 129a in Stewart's numbering system. He made 100 in 1998.
