Nakayama proposed to classify finite-dimensional algebras R over a field according to how long an exact sequence

of projective and injective R-R-bimodules Xi they allow. He conjectured that if there exists an infinite sequence of this type, then R must be quasi-Frobenius; and he proved this when R is generalized uniserial (17).
