% 3.64/0.88  % SZS output start Proof
% 3.64/0.88  Take the following subset of the input axioms:
% 3.64/0.88    fof(cn_18, axiom, ![X, Y]: is_a_theorem(implies(X, implies(Y, X)))).
% 3.64/0.88    fof(cn_35, axiom, ![Z, X2, Y2]: is_a_theorem(implies(implies(X2, implies(Y2, Z)), implies(implies(X2, Y2), implies(X2, Z))))).
% 3.64/0.88    fof(condensed_detachment, axiom, ![X2, Y2]: (~is_a_theorem(implies(X2, Y2)) | (~is_a_theorem(X2) | is_a_theorem(Y2)))).
% 3.64/0.88    fof(prove_cn_1, negated_conjecture, ~is_a_theorem(implies(implies(a, b), implies(implies(b, c), implies(a, c))))).
% 3.64/0.88  
% 3.64/0.88  Now clausify the problem and encode Horn clauses using encoding 3 of
% 3.64/0.88  http://www.cse.chalmers.se/~nicsma/papers/horn.pdf.
% 3.64/0.88  We repeatedly replace C & s=t => u=v by the two clauses:
% 3.64/0.88    fresh(y, y, x1...xn) = u
% 3.64/0.88    C => fresh(s, t, x1...xn) = v
% 3.64/0.88  where fresh is a fresh function symbol and x1..xn are the free
% 3.64/0.88  variables of u and v.
% 3.64/0.88  A predicate p(X) is encoded as p(X)=true (this is sound, because the
% 3.64/0.88  input problem has no model of domain size 1).
% 3.64/0.88  
% 3.64/0.88  The encoding turns the above axioms into the following unit equations and goals:
% 3.64/0.88  
% 3.64/0.88  Axiom 1 (condensed_detachment): fresh2(X, X, Y) = true.
% 3.64/0.88  Axiom 2 (condensed_detachment): fresh(X, X, Y, Z) = is_a_theorem(Z).
% 3.64/0.88  Axiom 3 (cn_18): is_a_theorem(implies(X, implies(Y, X))) = true.
% 3.64/0.88  Axiom 4 (condensed_detachment): fresh(is_a_theorem(implies(X, Y)), true, X, Y) = fresh2(is_a_theorem(X), true, Y).
