Multiparameter quantum supergroups

This paper is supplementary to my paper ``Multiparameter Quantum Groups and Multiparameter $R$-Matrices'', [5]. Its main purpose is to point out that among the single block solutions of the Yang-Baxter equation given in [5] there occurs an ${n+m choose 2 +1$ parameter quantum deformation of the supergroup $GL (m|n)$ for every $n,m geq 1$.
