% 4.28/0.95  % SZS status Theorem
% 4.28/0.95  
% 4.28/0.95  % SZS output start Proof
% 4.28/0.95  Take the following subset of the input axioms:
% 4.28/0.95    fof(m__, conjecture, sdtlpdtrp0(xc, xQ)=szDzizrdt0(xd)).
% 4.28/0.95    fof(m__5321, hypothesis, sdtlpdtrp0(xd, xn)=szDzizrdt0(xd)).
% 4.28/0.95    fof(m__5568, hypothesis, sdtlpdtrp0(xc, xQ)=sdtlpdtrp0(xd, xn)).
% 4.28/0.95  
% 4.28/0.95  Now clausify the problem and encode Horn clauses using encoding 3 of
% 4.28/0.95  http://www.cse.chalmers.se/~nicsma/papers/horn.pdf.
% 4.28/0.95  We repeatedly replace C & s=t => u=v by the two clauses:
% 4.28/0.95    fresh(y, y, x1...xn) = u
% 4.28/0.95    C => fresh(s, t, x1...xn) = v
% 4.28/0.95  where fresh is a fresh function symbol and x1..xn are the free
% 4.28/0.95  variables of u and v.
% 4.28/0.95  A predicate p(X) is encoded as p(X)=true (this is sound, because the
% 4.28/0.95  input problem has no model of domain size 1).
% 4.28/0.95  
% 4.28/0.95  The encoding turns the above axioms into the following unit equations and goals:
% 4.28/0.95  
% 4.28/0.95  Axiom 1 (m__5568): sdtlpdtrp0(xc, xQ) = sdtlpdtrp0(xd, xn).
% 4.28/0.95  Axiom 2 (m__5321): sdtlpdtrp0(xd, xn) = szDzizrdt0(xd).
% 4.28/0.95  
% 4.28/0.95  Goal 1 (m__): sdtlpdtrp0(xc, xQ) = szDzizrdt0(xd).
% 4.28/0.95  Proof:
% 4.28/0.95    sdtlpdtrp0(xc, xQ)
% 4.28/0.95  = { by axiom 1 (m__5568) }
% 4.28/0.95    sdtlpdtrp0(xd, xn)
% 4.28/0.95  = { by axiom 2 (m__5321) }
% 4.28/0.95    szDzizrdt0(xd)
% 4.28/0.95  % SZS output end Proof
% 4.28/0.95  
% 4.28/0.95  RESULT: Theorem (the conjecture is true).
