Using de Morgan's laws in the calculus of fuzzy sets the author discusses notions dual to level sets of fuzzy sets and to fuzzy groups [cf. \textit{P. S. Das}, J. Math. Anal. Appl. 84, 264-269 (1981; Zbl 0476.20002)]. The de Morgan complement of a fuzzy group is called here ``anti fuzzy group'' (without any algebraic analogy).
