% 8.07/1.42  % SZS output start Proof
% 8.07/1.42  Take the following subset of the input axioms:
% 8.07/1.43    fof(mZeroLess, axiom, ![W0]: (aElementOf0(W0, szNzAzT0) => sdtlseqdt0(sz00, W0))).
% 8.07/1.43    fof(mZeroNum, axiom, aElementOf0(sz00, szNzAzT0)).
% 8.07/1.43    fof(m__, conjecture, ![W0_2]: (aElementOf0(W0_2, sdtlpdtrp0(xN, xi)) => aElementOf0(W0_2, xS)) | aSubsetOf0(sdtlpdtrp0(xN, xi), xS)).
% 8.07/1.43    fof(m__3623, hypothesis, aFunction0(xN) & (szDzozmdt0(xN)=szNzAzT0 & (sdtlpdtrp0(xN, sz00)=xS & ![W0_2]: (aElementOf0(W0_2, szNzAzT0) => ((((aSet0(sdtlpdtrp0(xN, W0_2)) & ![W1]: (aElementOf0(W1, sdtlpdtrp0(xN, W0_2)) => aElementOf0(W1, szNzAzT0))) | aSubsetOf0(sdtlpdtrp0(xN, W0_2), szNzAzT0)) & isCountable0(sdtlpdtrp0(xN, W0_2))) => (aElementOf0(szmzizndt0(sdtlpdtrp0(xN, W0_2)), sdtlpdtrp0(xN, W0_2)) & (![W1_2]: (aElementOf0(W1_2, sdtlpdtrp0(xN, W0_2)) => sdtlseqdt0(szmzizndt0(sdtlpdtrp0(xN, W0_2)), W1_2)) & (aSet0(sdtmndt0(sdtlpdtrp0(xN, W0_2), szmzizndt0(sdtlpdtrp0(xN, W0_2)))) & (![W1_2]: (aElementOf0(W1_2, sdtmndt0(sdtlpdtrp0(xN, W0_2), szmzizndt0(sdtlpdtrp0(xN, W0_2)))) <=> (aElement0(W1_2) & (aElementOf0(W1_2, sdtlpdtrp0(xN, W0_2)) & W1_2!=szmzizndt0(sdtlpdtrp0(xN, W0_2))))) & (aSet0(sdtlpdtrp0(xN, szszuzczcdt0(W0_2))) & (![W1_2]: (aElementOf0(W1_2, sdtlpdtrp0(xN, szszuzczcdt0(W0_2))) => aElementOf0(W1_2, sdtmndt0(sdtlpdtrp0(xN, W0_2), szmzizndt0(sdtlpdtrp0(xN, W0_2))))) & (aSubsetOf0(sdtlpdtrp0(xN, szszuzczcdt0(W0_2)), sdtmndt0(sdtlpdtrp0(xN, W0_2), szmzizndt0(sdtlpdtrp0(xN, W0_2)))) & isCountable0(sdtlpdtrp0(xN, szszuzczcdt0(W0_2))))))))))))))).
% 8.07/1.43    fof(m__3754, hypothesis, ![W0_2, W1_2]: ((aElementOf0(W0_2, szNzAzT0) & aElementOf0(W1_2, szNzAzT0)) => (sdtlseqdt0(W1_2, W0_2) => (![W2]: (aElementOf0(W2, sdtlpdtrp0(xN, W0_2)) => aElementOf0(W2, sdtlpdtrp0(xN, W1_2))) & aSubsetOf0(sdtlpdtrp0(xN, W0_2), sdtlpdtrp0(xN, W1_2)))))).
% 8.07/1.43    fof(m__3989, hypothesis, aElementOf0(xi, szNzAzT0)).
% 8.07/1.43  
% 8.07/1.43  Now clausify the problem and encode Horn clauses using encoding 3 of
% 8.07/1.43  http://www.cse.chalmers.se/~nicsma/papers/horn.pdf.
% 8.07/1.43  We repeatedly replace C & s=t => u=v by the two clauses:
% 8.07/1.43    fresh(y, y, x1...xn) = u
% 8.07/1.43    C => fresh(s, t, x1...xn) = v
% 8.07/1.43  where fresh is a fresh function symbol and x1..xn are the free
% 8.07/1.43  variables of u and v.
% 8.07/1.43  A predicate p(X) is encoded as p(X)=true (this is sound, because the
% 8.07/1.43  input problem has no model of domain size 1).
% 8.07/1.43  
% 8.07/1.43  The encoding turns the above axioms into the following unit equations and goals:
% 8.07/1.43  
% 8.07/1.43  Axiom 1 (m__3989): aElementOf0(xi, szNzAzT0) = true2.
% 8.07/1.43  Axiom 2 (mZeroNum): aElementOf0(sz00, szNzAzT0) = true2.
% 8.07/1.43  Axiom 3 (m__3623_1): sdtlpdtrp0(xN, sz00) = xS.
% 8.07/1.43  Axiom 4 (mZeroLess): fresh69(X, X, Y) = true2.
% 8.07/1.43  Axiom 5 (m__3754_1): fresh172(X, X, Y, Z) = true2.
% 8.07/1.43  Axiom 6 (mZeroLess): fresh69(aElementOf0(X, szNzAzT0), true2, X) = sdtlseqdt0(sz00, X).
% 8.07/1.43  Axiom 7 (m__3754_1): fresh17(X, X, Y, Z) = aSubsetOf0(sdtlpdtrp0(xN, Y), sdtlpdtrp0(xN, Z)).
% 8.07/1.43  Axiom 8 (m__3754_1): fresh171(X, X, Y, Z) = fresh172(aElementOf0(Y, szNzAzT0), true2, Y, Z).
% 8.07/1.43  Axiom 9 (m__3754_1): fresh171(sdtlseqdt0(X, Y), true2, Y, X) = fresh17(aElementOf0(X, szNzAzT0), true2, Y, X).
% 8.07/1.43  
% 8.07/1.43  Goal 1 (m___2): aSubsetOf0(sdtlpdtrp0(xN, xi), xS) = true2.
% 8.07/1.43  Proof:
% 8.07/1.43    aSubsetOf0(sdtlpdtrp0(xN, xi), xS)
% 8.07/1.43  = { by axiom 3 (m__3623_1) R->L }
% 8.07/1.43    aSubsetOf0(sdtlpdtrp0(xN, xi), sdtlpdtrp0(xN, sz00))
% 8.07/1.43  = { by axiom 7 (m__3754_1) R->L }
% 8.07/1.43    fresh17(true2, true2, xi, sz00)
% 8.07/1.43  = { by axiom 2 (mZeroNum) R->L }
% 8.07/1.43    fresh17(aElementOf0(sz00, szNzAzT0), true2, xi, sz00)
% 8.07/1.43  = { by axiom 9 (m__3754_1) R->L }
% 8.07/1.43    fresh171(sdtlseqdt0(sz00, xi), true2, xi, sz00)
% 8.07/1.43  = { by axiom 6 (mZeroLess) R->L }
% 8.07/1.43    fresh171(fresh69(aElementOf0(xi, szNzAzT0), true2, xi), true2, xi, sz00)
% 8.07/1.43  = { by axiom 1 (m__3989) }
% 8.07/1.43    fresh171(fresh69(true2, true2, xi), true2, xi, sz00)
% 8.07/1.43  = { by axiom 4 (mZeroLess) }
% 8.07/1.43    fresh171(true2, true2, xi, sz00)
% 8.07/1.43  = { by axiom 8 (m__3754_1) }
% 8.07/1.43    fresh172(aElementOf0(xi, szNzAzT0), true2, xi, sz00)
% 8.07/1.43  = { by axiom 1 (m__3989) }
% 8.07/1.43    fresh172(true2, true2, xi, sz00)
% 8.07/1.43  = { by axiom 5 (m__3754_1) }
% 8.07/1.43    true2
% 8.07/1.43  % SZS output end Proof
% 8.07/1.43  
% 8.07/1.43  RESULT: Theorem (the conjecture is true).
