% 26.47/3.79  % SZS output start Proof
% 26.47/3.79  Take the following subset of the input axioms:
% 26.47/3.80    fof(cls_CHAINED_0, axiom, c_Type_Otypings(v_e____, c_List_Omap(hAPP(c_COMBC(hAPP(c_COMBC(c_Lambda_Osubst, tc_Lambda_OdB, tc_Lambda_OdB, tc_fun(tc_nat, tc_Lambda_OdB)), v_u____), tc_Lambda_OdB, tc_nat, tc_Lambda_OdB), v_i____), v_as____, tc_Lambda_OdB, tc_Lambda_OdB), v_Ts____)).
% 26.47/3.80    fof(cls_conjecture_0, negated_conjecture, ~c_Type_Otypings(c_Type_Oshift(v_e____, c_HOL_Ozero__class_Ozero(tc_nat), c_List_Ofoldr(c_Type_Otype_OFun, v_Ts____, v_T_H____, tc_Type_Otype, tc_Type_Otype), tc_Type_Otype), c_List_Omap(hAPP(c_COMBC(c_Lambda_Olift, tc_Lambda_OdB, tc_nat, tc_Lambda_OdB), c_HOL_Ozero__class_Ozero(tc_nat)), c_List_Omap(hAPP(c_COMBC(hAPP(c_COMBC(c_Lambda_Osubst, tc_Lambda_OdB, tc_Lambda_OdB, tc_fun(tc_nat, tc_Lambda_OdB)), v_u____), tc_Lambda_OdB, tc_nat, tc_Lambda_OdB), v_i____), v_as____, tc_Lambda_OdB, tc_Lambda_OdB), tc_Lambda_OdB, tc_Lambda_OdB), v_Ts____)).
% 26.47/3.80    fof(cls_lift__types_0, axiom, ![V_i, V_e, V_ts, V_U, V_Ts]: (c_Type_Otypings(c_Type_Oshift(V_e, V_i, V_U, tc_Type_Otype), c_List_Omap(hAPP(c_COMBC(c_Lambda_Olift, tc_Lambda_OdB, tc_nat, tc_Lambda_OdB), V_i), V_ts, tc_Lambda_OdB, tc_Lambda_OdB), V_Ts) | ~c_Type_Otypings(V_e, V_ts, V_Ts))).
% 26.47/3.80  
% 26.47/3.80  Now clausify the problem and encode Horn clauses using encoding 3 of
% 26.47/3.80  http://www.cse.chalmers.se/~nicsma/papers/horn.pdf.
% 26.47/3.80  We repeatedly replace C & s=t => u=v by the two clauses:
% 26.47/3.80    fresh(y, y, x1...xn) = u
% 26.47/3.80    C => fresh(s, t, x1...xn) = v
% 26.47/3.80  where fresh is a fresh function symbol and x1..xn are the free
% 26.47/3.80  variables of u and v.
% 26.47/3.80  A predicate p(X) is encoded as p(X)=true (this is sound, because the
% 26.47/3.80  input problem has no model of domain size 1).
% 26.47/3.80  
% 26.47/3.80  The encoding turns the above axioms into the following unit equations and goals:
% 26.47/3.80  
% 26.47/3.80  Axiom 1 (cls_lift__types_0): fresh305(X, X, Y, Z, W, V, U) = true2.
% 26.47/3.80  Axiom 2 (cls_lift__types_0): fresh305(c_Type_Otypings(X, Y, Z), true2, X, W, V, Y, Z) = c_Type_Otypings(c_Type_Oshift(X, W, V, tc_Type_Otype), c_List_Omap(hAPP(c_COMBC(c_Lambda_Olift, tc_Lambda_OdB, tc_nat, tc_Lambda_OdB), W), Y, tc_Lambda_OdB, tc_Lambda_OdB), Z).
% 26.47/3.80  Axiom 3 (cls_CHAINED_0): c_Type_Otypings(v_e____, c_List_Omap(hAPP(c_COMBC(hAPP(c_COMBC(c_Lambda_Osubst, tc_Lambda_OdB, tc_Lambda_OdB, tc_fun(tc_nat, tc_Lambda_OdB)), v_u____), tc_Lambda_OdB, tc_nat, tc_Lambda_OdB), v_i____), v_as____, tc_Lambda_OdB, tc_Lambda_OdB), v_Ts____) = true2.
% 26.47/3.80  
% 26.47/3.80  Goal 1 (cls_conjecture_0): c_Type_Otypings(c_Type_Oshift(v_e____, c_HOL_Ozero__class_Ozero(tc_nat), c_List_Ofoldr(c_Type_Otype_OFun, v_Ts____, v_T_H____, tc_Type_Otype, tc_Type_Otype), tc_Type_Otype), c_List_Omap(hAPP(c_COMBC(c_Lambda_Olift, tc_Lambda_OdB, tc_nat, tc_Lambda_OdB), c_HOL_Ozero__class_Ozero(tc_nat)), c_List_Omap(hAPP(c_COMBC(hAPP(c_COMBC(c_Lambda_Osubst, tc_Lambda_OdB, tc_Lambda_OdB, tc_fun(tc_nat, tc_Lambda_OdB)), v_u____), tc_Lambda_OdB, tc_nat, tc_Lambda_OdB), v_i____), v_as____, tc_Lambda_OdB, tc_Lambda_OdB), tc_Lambda_OdB, tc_Lambda_OdB), v_Ts____) = true2.
% 26.47/3.80  Proof:
% 26.47/3.80    c_Type_Otypings(c_Type_Oshift(v_e____, c_HOL_Ozero__class_Ozero(tc_nat), c_List_Ofoldr(c_Type_Otype_OFun, v_Ts____, v_T_H____, tc_Type_Otype, tc_Type_Otype), tc_Type_Otype), c_List_Omap(hAPP(c_COMBC(c_Lambda_Olift, tc_Lambda_OdB, tc_nat, tc_Lambda_OdB), c_HOL_Ozero__class_Ozero(tc_nat)), c_List_Omap(hAPP(c_COMBC(hAPP(c_COMBC(c_Lambda_Osubst, tc_Lambda_OdB, tc_Lambda_OdB, tc_fun(tc_nat, tc_Lambda_OdB)), v_u____), tc_Lambda_OdB, tc_nat, tc_Lambda_OdB), v_i____), v_as____, tc_Lambda_OdB, tc_Lambda_OdB), tc_Lambda_OdB, tc_Lambda_OdB), v_Ts____)

% 26.47/3.80  = { by axiom 3 (cls_CHAINED_0) }
% 26.47/3.80    fresh305(true2, true2, v_e____, c_HOL_Ozero__class_Ozero(tc_nat), c_List_Ofoldr(c_Type_Otype_OFun, v_Ts____, v_T_H____, tc_Type_Otype, tc_Type_Otype), c_List_Omap(hAPP(c_COMBC(hAPP(c_COMBC(c_Lambda_Osubst, tc_Lambda_OdB, tc_Lambda_OdB, tc_fun(tc_nat, tc_Lambda_OdB)), v_u____), tc_Lambda_OdB, tc_nat, tc_Lambda_OdB), v_i____), v_as____, tc_Lambda_OdB, tc_Lambda_OdB), v_Ts____)
% 26.47/3.80  = { by axiom 1 (cls_lift__types_0) }
% 26.47/3.80    true2
% 26.47/3.80  % SZS output end Proof
% 26.47/3.80  
% 26.47/3.80  RESULT: Unsatisfiable (the axioms are contradictory).
