% 0.21/0.47  % SZS output start Proof
% 0.21/0.47  Take the following subset of the input axioms:
% 0.21/0.47    fof(owl_char_transitive, axiom, ![P]: (icext(uri_owl_TransitiveProperty, P) <=> (ip(P) & ![X, Z, Y]: ((iext(P, X, Y) & iext(P, Y, Z)) => iext(P, X, Z))))).
% 0.21/0.47    fof(owl_rdfsext_subclassof, axiom, ![C1, C2]: (iext(uri_rdfs_subClassOf, C1, C2) <=> (ic(C1) & (ic(C2) & ![X2]: (icext(C1, X2) => icext(C2, X2)))))).
% 0.21/0.47    fof(owl_restrict_mincard_001, axiom, ![Z2, P2]: ((iext(uri_owl_minCardinality, Z2, literal_typed(dat_str_1, uri_xsd_nonNegativeInteger)) & iext(uri_owl_onProperty, Z2, P2)) => ![X2]: (icext(Z2, X2) <=> ?[Y2]: iext(P2, X2, Y2)))).
% 0.21/0.47    fof(rdfs_cext_def, axiom, ![C, X2]: (iext(uri_rdf_type, X2, C) <=> icext(C, X2))).
% 0.21/0.47    fof(testcase_conclusion_fullish_024_Cardinality_Restrictions_on_Complex_Properties, conjecture, ?[BNODE_x]: (iext(uri_ex_hasAncestor, uri_ex_bob, BNODE_x) & iext(uri_ex_hasAncestor, uri_ex_alice, BNODE_x))).
% 0.21/0.47    fof(testcase_premise_fullish_024_Cardinality_Restrictions_on_Complex_Properties, axiom, ?[BNODE_z]: (iext(uri_rdf_type, uri_ex_hasAncestor, uri_owl_TransitiveProperty) & (iext(uri_rdfs_subClassOf, uri_ex_Person, BNODE_z) & (iext(uri_rdf_type, BNODE_z, uri_owl_Restriction) & (iext(uri_owl_onProperty, BNODE_z, uri_ex_hasAncestor) & (iext(uri_owl_minCardinality, BNODE_z, literal_typed(dat_str_1, uri_xsd_nonNegativeInteger)) & (iext(uri_rdf_type, uri_ex_alice, uri_ex_Person) & (iext(uri_rdf_type, uri_ex_bob, uri_ex_Person) & iext(uri_ex_hasAncestor, uri_ex_alice, uri_ex_bob))))))))).
% 0.21/0.47  
% 0.21/0.47  Now clausify the problem and encode Horn clauses using encoding 3 of
% 0.21/0.47  http://www.cse.chalmers.se/~nicsma/papers/horn.pdf.
% 0.21/0.47  We repeatedly replace C & s=t => u=v by the two clauses:
% 0.21/0.47    fresh(y, y, x1...xn) = u
% 0.21/0.47    C => fresh(s, t, x1...xn) = v
% 0.21/0.47  where fresh is a fresh function symbol and x1..xn are the free
% 0.21/0.47  variables of u and v.
% 0.21/0.47  A predicate p(X) is encoded as p(X)=true (this is sound, because the
% 0.21/0.47  input problem has no model of domain size 1).
% 0.21/0.47  
% 0.21/0.47  The encoding turns the above axioms into the following unit equations and goals:
% 0.21/0.47  
% 0.21/0.47  Axiom 1 (testcase_premise_fullish_024_Cardinality_Restrictions_on_Complex_Properties): iext(uri_rdf_type, uri_ex_hasAncestor, uri_owl_TransitiveProperty) = true2.

% 0.21/0.48  Axiom 3 (testcase_premise_fullish_024_Cardinality_Restrictions_on_Complex_Properties_6): iext(uri_rdfs_subClassOf, uri_ex_Person, bnode_z) = true2.

% 0.21/0.48  Axiom 14 (owl_rdfsext_subclassof_2): fresh7(icext(X, Y), true2, X, Z, Y) = fresh6(iext(uri_rdfs_subClassOf, X, Z), true2, Z, Y).
% 0.21/0.48  Axiom 15 (rdfs_cext_def): fresh2(iext(uri_rdf_type, X, Y), true2, X, Y) = icext(Y, X).
