A triple of positive integers satisfying is said to be harmonic if
In particular, such a triple is harmonic if the reciprocals of its terms form an arithmetic sequence with common difference where
One can show that there exists a one-to-one correspondence between the set of equivalence classes of harmonic triples and the set of equivalence classes of geometric triples where here, two triples and are said to be equivalent if , i.e., if there exists some positive real number such that .
