% 206.64/26.80  % SZS output start Proof
% 206.64/26.80  Take the following subset of the input axioms:
% 206.64/26.80    fof(cn_1, axiom, ![X, Y, Z]: is_a_theorem(implies(implies(X, Y), implies(implies(Y, Z), implies(X, Z))))).
% 206.64/26.80    fof(cn_2, axiom, ![X2]: is_a_theorem(implies(implies(not(X2), X2), X2))).
% 206.64/26.80    fof(cn_3, axiom, ![X2, Y2]: is_a_theorem(implies(X2, implies(not(X2), Y2)))).
% 206.64/26.80    fof(condensed_detachment, axiom, ![X2, Y2]: (~is_a_theorem(implies(X2, Y2)) | (~is_a_theorem(X2) | is_a_theorem(Y2)))).
% 206.64/26.80    fof(prove_cn_46, negated_conjecture, ~is_a_theorem(implies(implies(a, b), implies(not(b), not(a))))).
% 206.64/26.80  
% 206.64/26.80  Now clausify the problem and encode Horn clauses using encoding 3 of
% 206.64/26.80  http://www.cse.chalmers.se/~nicsma/papers/horn.pdf.
% 206.64/26.80  We repeatedly replace C & s=t => u=v by the two clauses:
% 206.64/26.80    fresh(y, y, x1...xn) = u
% 206.64/26.80    C => fresh(s, t, x1...xn) = v
% 206.64/26.80  where fresh is a fresh function symbol and x1..xn are the free
% 206.64/26.80  variables of u and v.
% 206.64/26.80  A predicate p(X) is encoded as p(X)=true (this is sound, because the
% 206.64/26.80  input problem has no model of domain size 1).
% 206.64/26.80  
% 206.64/26.80  The encoding turns the above axioms into the following unit equations and goals:
% 206.64/26.80  
% 206.64/26.80  Axiom 1 (condensed_detachment): fresh2(X, X, Y) = true.
% 206.64/26.80  Axiom 2 (condensed_detachment): fresh(X, X, Y, Z) = is_a_theorem(Z).
% 206.64/26.80  Axiom 3 (cn_3): is_a_theorem(implies(X, implies(not(X), Y))) = true.
% 206.64/26.80  Axiom 4 (cn_2): is_a_theorem(implies(implies(not(X), X), X)) = true.
% 206.64/26.80  Axiom 5 (condensed_detachment): fresh(is_a_theorem(implies(X, Y)), true, X, Y) = fresh2(is_a_theorem(X), true, Y).
% 206.64/26.80  Axiom 6 (cn_1): is_a_theorem(implies(implies(X, Y), implies(implies(Y, Z), implies(X, Z)))) = true.
