This paper is concerned with algebras generated by two idempotents P and Q satisfying (PQ ) m = (QP) m and (PQ ) m-1 = (QP) m-1 . The main result is the classification of all these algebras, implying that for each m ≥ 2 there exist exactly eight nonisomorphic copies. As an application, it is shown t
