% 3.88/0.91  % SZS output start Proof
% 3.88/0.91  Take the following subset of the input axioms:
% 3.88/0.91    fof(mDistr2, axiom, ![W0, W1, W2, W3]: ((aScalar0(W0) & (aScalar0(W1) & (aScalar0(W2) & aScalar0(W3)))) => sdtasdt0(sdtpldt0(W0, W1), sdtpldt0(W2, W3))=sdtpldt0(sdtpldt0(sdtasdt0(W0, W2), sdtasdt0(W0, W3)), sdtpldt0(sdtasdt0(W1, W2), sdtasdt0(W1, W3))))).
% 3.88/0.91    fof(m__, conjecture, sdtlseqdt0(sdtasdt0(sdtpldt0(xP, xP), sdtpldt0(xP, xP)), sdtasdt0(sdtpldt0(xR, xS), sdtpldt0(xR, xS)))).
% 3.88/0.91    fof(m__1892, hypothesis, aScalar0(xR) & xR=sdtasdt0(xC, xG)).
% 3.88/0.91    fof(m__1911, hypothesis, aScalar0(xP) & xP=sdtasdt0(xE, xH)).
% 3.88/0.91    fof(m__1930, hypothesis, aScalar0(xS) & xS=sdtasdt0(xF, xD)).
% 3.88/0.91    fof(m__2580, hypothesis, sdtlseqdt0(sdtpldt0(sdtpldt0(sdtasdt0(xP, xP), sdtasdt0(xP, xP)), sdtpldt0(sdtasdt0(xP, xP), sdtasdt0(xP, xP))), sdtpldt0(sdtpldt0(sdtasdt0(xR, xR), sdtasdt0(xR, xS)), sdtpldt0(sdtasdt0(xS, xR), sdtasdt0(xS, xS))))).
% 3.88/0.91  
% 3.88/0.91  Now clausify the problem and encode Horn clauses using encoding 3 of
% 3.88/0.91  http://www.cse.chalmers.se/~nicsma/papers/horn.pdf.
% 3.88/0.91  We repeatedly replace C & s=t => u=v by the two clauses:
% 3.88/0.91    fresh(y, y, x1...xn) = u
% 3.88/0.91    C => fresh(s, t, x1...xn) = v
% 3.88/0.91  where fresh is a fresh function symbol and x1..xn are the free
% 3.88/0.91  variables of u and v.
% 3.88/0.91  A predicate p(X) is encoded as p(X)=true (this is sound, because the
% 3.88/0.91  input problem has no model of domain size 1).
% 3.88/0.91  
% 3.88/0.91  The encoding turns the above axioms into the following unit equations and goals:
% 3.88/0.91  
% 3.88/0.91  Axiom 1 (m__1911_1): aScalar0(xP) = true2.
% 3.88/0.91  Axiom 2 (m__1892_1): aScalar0(xR) = true2.
% 3.88/0.91  Axiom 3 (m__1930_1): aScalar0(xS) = true2.
% 3.88/0.91  Axiom 4 (mDistr): fresh33(X, X, Y, Z, W) = sdtpldt0(sdtasdt0(Y, Z), sdtasdt0(Y, W)).
% 3.88/0.91  Axiom 5 (mDistr2): fresh86(X, X, Y, Z, W, V) = sdtasdt0(sdtpldt0(Y, Z), sdtpldt0(W, V)).
% 3.88/0.91  Axiom 6 (mDistr2): fresh85(X, X, Y, Z, W, V) = fresh86(aScalar0(Y), true2, Y, Z, W, V).
% 3.88/0.91  Axiom 7 (mDistr2): fresh84(X, X, Y, Z, W, V) = fresh85(aScalar0(Z), true2, Y, Z, W, V).
% 3.88/0.91  Axiom 8 (mDistr2): fresh83(X, X, Y, Z, W, V) = fresh84(aScalar0(W), true2, Y, Z, W, V).
% 3.88/0.91  Axiom 9 (mDistr2): fresh83(aScalar0(X), true2, Y, Z, W, X) = sdtpldt0(sdtpldt0(sdtasdt0(Y, W), sdtasdt0(Y, X)), sdtpldt0(sdtasdt0(Z, W), sdtasdt0(Z, X))).
% 3.88/0.91  Axiom 10 (m__2580): sdtlseqdt0(sdtpldt0(sdtpldt0(sdtasdt0(xP, xP), sdtasdt0(xP, xP)), sdtpldt0(sdtasdt0(xP, xP), sdtasdt0(xP, xP))), sdtpldt0(sdtpldt0(sdtasdt0(xR, xR), sdtasdt0(xR, xS)), sdtpldt0(sdtasdt0(xS, xR), sdtasdt0(xS, xS)))) = true2.
% 3.88/0.91  
% 3.88/0.91  Lemma 11: sdtpldt0(fresh33(X, X, Y, Z, W), fresh33(V, V, U, Z, W)) = fresh83(aScalar0(W), true2, Y, U, Z, W).
% 3.88/0.91  Proof:
% 3.88/0.91    sdtpldt0(fresh33(X, X, Y, Z, W), fresh33(V, V, U, Z, W))
% 3.88/0.91  = { by axiom 4 (mDistr) }

% 3.88/0.91    fresh83(aScalar0(W), true2, Y, U, Z, W)
% 3.88/0.91
