We describe some salient features of the 331F (Frampton-Pisano-Pleitez) bilepton model, in which the constraints of anomaly cancelation require the number of generations to be three. In a class of six models, four of which characterised by a β parameter describing the embedding of the hypercharge in the SU(3)L symmetry, a specific choice for β allows bileptons in the spectrum, i.e. vectors and scalars of lepton numbers ±2. At the same time the model allows exotic quarks, with the third quark generation treated asymmetrically respect to the other two. Bileptons generate specific signatures in the form of multilepton final states in Drell-Yan like processes, with and without associated jets, which can be searched for at the LHC.
