The building set also includes secondary and tertiary building members. The secondary building members have elongated bodies and a second type of coupling including coupling faces that are at least partly rotational-symmetric about an axis transverse to the longitudinal direction of the body and coupling faces adapted to grip and receive the aforementioned coupling faces. The tertiary building members include a coupling of each of the primary and secondary types.
