Popis:	In this article, we answer positively an open question posed in [G. Mayor, J. Suner, and J. Torrens, “Copula-like operations on finite settings,” IEEE Trans. Fuzzy Syst. , vol. 13, no. 4, pp. 468–477, Aug. 2005] concerning the extensions of discrete copulas to shuffles of Min. Moreover, we also use the extension of discrete copulas to sparse copulas, associated with discrete copulas, of idempotent copulas, in particular, the copula $M$ , in order to answer the open question in an alternative way.
