This artwork consists of three right-handed zigzagzeg (order-3) helixes on the outside and three tighter left-handed zigzagzeg helixes on the inside,
connected into a single loop.
In this replica, the beam has been slightly reduced in thickness to introduce a narrow gap between adjacent beams.
The original is in wood. It is used as annual trophy in the Dutch Olympiad in Informatics.
