Summary: Let \((A,\mathfrak m)\) be a regular local ring and let \(M\subseteq F=A^d\) be the second syzygy module of the residue field. We introduce the concept of generalized Grassmann algebras and investigate the Rees algebra \(R(M)\) of \(M\). We explore the propertie of generalized Grassmann algebras and prove that the Rees algebra \(R(M)\) of the second syzygy module \(M\) is a Gorenstein factorial domain.
