Abstract
A class of supersymmetric preon models is considered in which the hypercolour groupG HC and the unbroken flavour groupG f anomalies are zero without needing spectators. It is shown that forG HC=SU(2) and SU(3) quarks and leptons as composites can be obtained satisfying ’t Hooft’s anomaly matching conditions. For the case ofG HC=SU(3),G f can accommodate a horizontal symmetry group to describe just three generations.
