WordNet records no synonym and no antonym for conducting. It is the only member of each of its synsets, which is common for technical, taxonomic and single-sense vocabulary — there is no other English word that means the same thing. The broader and narrower terms below are the useful relations in that case.
Counts are distinct word forms across every sense. A synonym that appears under three senses is counted once here and shown three times below, under each sense it belongs to.
the way of administering a business
the direction of an orchestra or choir
“he does not use a baton for conducting”
