Maybe this one (OWL 1)?

"""
ex:c owl:unionOf ( ex:c1 ex:c2 ex:c3 ) .
ex:d owl:disjointWith ex:c1 .
ex:d rdfs:subClassOf [ 
    owl:intersectionOf ( ex:c [ owl:complementOf ex:c2 ] ) 
] .
---------------------------------------
ex:d rdfs:subClassOf ex:c3 .
"""

Or that one (OWL 2)?

"""
ex:p rdf:type owl:ObjectProperty .
ex:s rdf:type [
    rdf:type owl:Restriction ;
    owl:onProperty ex:p ;
    owl:allValuesFrom [

            owl:oneOf ( ex:o )
