    The bimodule resolutions of basic self-injective Nakayama algebras have been shown to be periodic by \textit{K. Erdmann} and \textit{T. Holm} [Forum Math. 11, No. 2, 177-201 (1999; Zbl 0937.16014)]. In the paper under review, subalgebras are defined, which are generated by paths of fixed length in the (cyclic) quiver. These subalgebras are shown to decompose into direct sums of basic Nakayama algebras. Thus again these algebras have periodic bimodule resolutions, which are given explicitly.
