% 0.19/0.46  % SZS output start Proof
% 0.19/0.46  Take the following subset of the input axioms:
% 0.19/0.46    fof(not_p7_26, negated_conjecture, ~p7(f8(f10(f12(f11(f3(f5(c17)))), c18), f8(f10(f11(f3(f4(f5(c17)))), c21), f9(f11(c19), f10(f11(f3(f4(f5(c17)))), c22)))), f8(f10(f12(f11(f3(f5(c17)))), c23), f8(f10(f11(f3(f4(f5(c17)))), c25), f9(f11(c24), f10(f11(f3(f4(f5(c17)))), c22)))))).
% 0.19/0.46    fof(p7_14, negated_conjecture, ![X25, X26, X27]: (p7(X26, X27) | (~p7(X25, X26) | ~p7(X25, X27)))).
% 0.19/0.46    fof(p7_2, negated_conjecture, ![X25_2]: p7(X25_2, X25_2)).
% 0.19/0.46    fof(p7_24, negated_conjecture, p7(c20, f8(f10(f12(f11(f3(f5(c17)))), c23), f8(f10(f11(f3(f4(f5(c17)))), c25), f9(f11(c24), f10(f11(f3(f4(f5(c17)))), c22)))))).
% 0.19/0.46    fof(p7_25, negated_conjecture, p7(c20, f8(f10(f12(f11(f3(f5(c17)))), c18), f8(f10(f11(f3(f4(f5(c17)))), c21), f9(f11(c19), f10(f11(f3(f4(f5(c17)))), c22)))))).
% 0.19/0.46  
% 0.19/0.46  Now clausify the problem and encode Horn clauses using encoding 3 of
% 0.19/0.46  http://www.cse.chalmers.se/~nicsma/papers/horn.pdf.
% 0.19/0.46  We repeatedly replace C & s=t => u=v by the two clauses:
% 0.19/0.46    fresh(y, y, x1...xn) = u
% 0.19/0.46    C => fresh(s, t, x1...xn) = v
% 0.19/0.46  where fresh is a fresh function symbol and x1..xn are the free
% 0.19/0.46  variables of u and v.
% 0.19/0.46  A predicate p(X) is encoded as p(X)=true (this is sound, because the
% 0.19/0.46  input problem has no model of domain size 1).
% 0.19/0.46  
% 0.19/0.46  The encoding turns the above axioms into the following unit equations and goals:
% 0.19/0.46  
% 0.19/0.46  Axiom 1 (p7_2): p7(X, X) = true.
% 0.19/0.46  Axiom 2 (p7_14): fresh8(X, X, Y, Z) = true.
% 0.19/0.46  Axiom 3 (p7_14): fresh9(X, X, Y, Z, W) = p7(Y, Z).
% 0.19/0.46  Axiom 4 (p7_14): fresh9(p7(X, Y), true, Z, Y, X) = fresh8(p7(X, Z), true, Z, Y).
% 0.19/0.46  Axiom 5 (p7_25): p7(c20, f8(f10(f12(f11(f3(f5(c17)))), c18), f8(f10(f11(f3(f4(f5(c17)))), c21), f9(f11(c19), f10(f11(f3(f4(f5(c17)))), c22))))) = true.
% 0.19/0.47  Axiom 6 (p7_24): p7(c20, f8(f10(f12(f11(f3(f5(c17)))), c23), f8(f10(f11(f3(f4(f5(c17)))), c25), f9(f11(c24), f10(f11(f3(f4(f5(c17)))), c22))))) = true.
% 0.19/0.47  
% 0.19/0.47  Goal 1 (not_p7_26): p7(f8(f10(f12(f11(f3(f5(c17)))), c18), f8(f10(f11(f3(f4(f5(c17)))), c21), f9(f11(c19), f10(f11(f3(f4(f5(c17)))), c22)))), f8(f10(f12(f11(f3(f5(c17)))), c23), f8(f10(f11(f3(f4(f5(c17)))), c25), f9(f11(c24), f10(f11(f3(f4(f5(c17)))), c22))))) = true.
