% 6.63/1.19  
% 6.63/1.19  % SZS output start Proof
% 6.63/1.19  Take the following subset of the input axioms:
% 6.63/1.19    fof(cls_argsT_0, axiom, c_Type_Otypings(c_Type_Oshift(v_e____, v_i____, v_T____, tc_Type_Otype), v_as____, v_Ts____)).
% 6.63/1.19    fof(cls_conjecture_0, negated_conjecture, ~c_List_Olistsp(c_COMBB(c_Ex(tc_Type_Otype), c_Type_Otyping(c_Type_Oshift(v_e____, v_i____, v_T____, tc_Type_Otype)), tc_fun(tc_Type_Otype, tc_bool), tc_bool, tc_Lambda_OdB), v_as____, tc_Lambda_OdB)).
% 6.63/1.19    fof(cls_lists__typings_0, axiom, ![V_e, V_ts, V_Ts]: (c_List_Olistsp(c_COMBB(c_Ex(tc_Type_Otype), c_Type_Otyping(V_e), tc_fun(tc_Type_Otype, tc_bool), tc_bool, tc_Lambda_OdB), V_ts, tc_Lambda_OdB) | ~c_Type_Otypings(V_e, V_ts, V_Ts))).
% 6.63/1.19  
% 6.63/1.19  Now clausify the problem and encode Horn clauses using encoding 3 of
% 6.63/1.19  http://www.cse.chalmers.se/~nicsma/papers/horn.pdf.
% 6.63/1.19  We repeatedly replace C & s=t => u=v by the two clauses:
% 6.63/1.19    fresh(y, y, x1...xn) = u
% 6.63/1.19    C => fresh(s, t, x1...xn) = v
% 6.63/1.19  where fresh is a fresh function symbol and x1..xn are the free
% 6.63/1.19  variables of u and v.
% 6.63/1.19  A predicate p(X) is encoded as p(X)=true (this is sound, because the
% 6.63/1.19  input problem has no model of domain size 1).
% 6.63/1.19  
% 6.63/1.19  The encoding turns the above axioms into the following unit equations and goals:
% 6.63/1.19  
% 6.63/1.19  Axiom 1 (cls_lists__typings_0): fresh111(X, X, Y, Z) = true2.
% 6.63/1.19  Axiom 2 (cls_argsT_0): c_Type_Otypings(c_Type_Oshift(v_e____, v_i____, v_T____, tc_Type_Otype), v_as____, v_Ts____) = true2.
% 6.63/1.19  Axiom 3 (cls_lists__typings_0): fresh111(c_Type_Otypings(X, Y, Z), true2, X, Y) = c_List_Olistsp(c_COMBB(c_Ex(tc_Type_Otype), c_Type_Otyping(X), tc_fun(tc_Type_Otype, tc_bool), tc_bool, tc_Lambda_OdB), Y, tc_Lambda_OdB).
% 6.63/1.19  
% 6.63/1.19  Goal 1 (cls_conjecture_0): c_List_Olistsp(c_COMBB(c_Ex(tc_Type_Otype), c_Type_Otyping(c_Type_Oshift(v_e____, v_i____, v_T____, tc_Type_Otype)), tc_fun(tc_Type_Otype, tc_bool), tc_bool, tc_Lambda_OdB), v_as____, tc_Lambda_OdB) = true2.
% 6.63/1.19  Proof:
% 6.63/1.19    c_List_Olistsp(c_COMBB(c_Ex(tc_Type_Otype), c_Type_Otyping(c_Type_Oshift(v_e____, v_i____, v_T____, tc_Type_Otype)), tc_fun(tc_Type_Otype, tc_bool), tc_bool, tc_Lambda_OdB), v_as____, tc_Lambda_OdB)
% 6.63/1.19  = { by axiom 3 (cls_lists__typings_0) R->L }
% 6.63/1.19    fresh111(c_Type_Otypings(c_Type_Oshift(v_e____, v_i____, v_T____, tc_Type_Otype), v_as____, v_Ts____), true2, c_Type_Oshift(v_e____, v_i____, v_T____, tc_Type_Otype), v_as____)
% 6.63/1.19  = { by axiom 2 (cls_argsT_0) }
% 6.63/1.19    fresh111(true2, true2, c_Type_Oshift(v_e____, v_i____, v_T____, tc_Type_Otype), v_as____)
% 6.63/1.19  = { by axiom 1 (cls_lists__typings_0) }
% 6.63/1.19    true2
% 6.63/1.19  % SZS output end Proof
% 6.63/1.19  
% 6.63/1.19  RESULT: Unsatisfiable (the axioms are contradictory).
