% 4.78/0.98  % SZS status Theorem
% 4.78/0.98  
% 4.78/0.98  % SZS output start Proof
% 4.78/0.98  Take the following subset of the input axioms:
% 4.78/0.98    fof(m__5538, hypothesis, aElementOf0(xp, xP) & $false).
% 4.78/0.98  
% 4.78/0.98  Now clausify the problem and encode Horn clauses using encoding 3 of
% 4.78/0.98  http://www.cse.chalmers.se/~nicsma/papers/horn.pdf.
% 4.78/0.98  We repeatedly replace C & s=t => u=v by the two clauses:
% 4.78/0.98    fresh(y, y, x1...xn) = u
% 4.78/0.98    C => fresh(s, t, x1...xn) = v
% 4.78/0.98  where fresh is a fresh function symbol and x1..xn are the free
% 4.78/0.98  variables of u and v.
% 4.78/0.98  A predicate p(X) is encoded as p(X)=true (this is sound, because the
% 4.78/0.98  input problem has no model of domain size 1).
% 4.78/0.98  
% 4.78/0.98  The encoding turns the above axioms into the following unit equations and goals:
% 4.78/0.98  
% 4.78/0.98  
% 4.78/0.98  Goal 1 (m__5538): tuple5 = tuple5.
% 4.78/0.98  Proof:
% 4.78/0.98  Reflexivity.
% 4.78/0.98  % SZS output end Proof
% 4.78/0.98  
% 4.78/0.98  RESULT: Theorem (the conjecture is true).
