Description from patent:
"A symmetrical assembly puzzle including a total of 12 elongated pieces having notched formed therein to receive other pieces of the puzzle. Nine of the pieces have two extra notches and the remaining three pieces have an extra, third notch. The pieces may be arranged in three solutions. In each solution, the assembled puzzle includes four groups of pieces, each group including three of the pieces. The pieces in an assembled group are oriented on parallel to each other but at an angle to the pieces in each of the other assembled groups."
