We consider the permutation \(f\) of antichains of a ranked poset \(P\), moving the set of lower units of any monotone boolean function on \(P\) to the set of its upper zeros. A duality relation on orbits of this permutation is found, which is used for proving a conjecture by M. Deza and K. Fukuda.
