tripeptide from 3 distinct amino acids                                                             20CX 3 = 3420 tripeptides
tripeptide from 3 alike  amino acids                                                                             20 trieptides
tripeptide from 2 alike and 1 distinct amino acid                                                   20CX 2  =380  tripeptides
                       Total = 3820 tripeptides
sorry, the previous answer was incorrect
