% 37.90/5.20  % SZS output start Proof
% 37.90/5.20  Take the following subset of the input axioms:
% 37.90/5.20    fof(ax1_122, axiom, mtvisible(c_tptpgeo_member7_mt) => borderson(c_georegion_l4_x27_y64, c_georegion_l4_x27_y65)).
% 37.90/5.20    fof(ax1_153, axiom, ![OBJ]: ~(tptpcol_1_1(OBJ) & tptpcol_1_65536(OBJ))).
% 37.90/5.20    fof(ax1_167, axiom, ![OBJ2]: ~(individual(OBJ2) & setorcollection(OBJ2))).
% 37.90/5.20    fof(ax1_289, axiom, ![OBJ2]: ~(collection(OBJ2) & individual(OBJ2))).
% 37.90/5.20    fof(ax1_3, axiom, ![OBJ2]: ~(intangible(OBJ2) & partiallytangible(OBJ2))).
% 37.90/5.20    fof(ax1_363, axiom, ![COL1, COL2, OBJ2]: ~(isa(OBJ2, COL1) & (isa(OBJ2, COL2) & disjointwith(COL1, COL2)))).
% 37.90/5.20    fof(ax1_488, axiom, ![OBJ2]: ~(tptpcol_3_98305(OBJ2) & tptpcol_3_114688(OBJ2))).
% 37.90/5.20    fof(ax1_521, axiom, ![X]: ~affiliatedwith(X, X)).
% 37.90/5.20    fof(ax1_698, axiom, ![X2]: ~objectfoundinlocation(X2, X2)).
% 37.90/5.20    fof(ax1_900, axiom, ![Y, X2]: (borderson(X2, Y) => borderson(Y, X2))).
% 37.90/5.20    fof(ax1_901, axiom, ![X2]: ~borderson(X2, X2)).
% 37.90/5.20    fof(query92, conjecture, ?[ARG1]: (mtvisible(c_tptpgeo_member7_mt) => borderson(ARG1, c_georegion_l4_x27_y64))).
% 37.90/5.20  
% 37.90/5.20  Now clausify the problem and encode Horn clauses using encoding 3 of
% 37.90/5.20  http://www.cse.chalmers.se/~nicsma/papers/horn.pdf.
% 37.90/5.20  We repeatedly replace C & s=t => u=v by the two clauses:
% 37.90/5.20    fresh(y, y, x1...xn) = u
% 37.90/5.20    C => fresh(s, t, x1...xn) = v
% 37.90/5.20  where fresh is a fresh function symbol and x1..xn are the free
% 37.90/5.20  variables of u and v.
% 37.90/5.20  A predicate p(X) is encoded as p(X)=true (this is sound, because the
% 37.90/5.20  input problem has no model of domain size 1).
% 37.90/5.20  
% 37.90/5.20  The encoding turns the above axioms into the following unit equations and goals:
% 37.90/5.20  
% 37.90/5.20  Axiom 1 (query92): mtvisible(c_tptpgeo_member7_mt) = true2.
% 37.90/5.20  Axiom 2 (ax1_122): fresh667(X, X) = true2.
% 37.90/5.20  Axiom 3 (ax1_122): fresh667(mtvisible(c_tptpgeo_member7_mt), true2) = borderson(c_georegion_l4_x27_y64, c_georegion_l4_x27_y65).
% 37.90/5.20  Axiom 4 (ax1_900): fresh93(X, X, Y, Z) = true2.
% 37.90/5.20  Axiom 5 (ax1_900): fresh93(borderson(X, Y), true2, X, Y) = borderson(Y, X).
% 37.90/5.20  
% 37.90/5.20  Goal 1 (query92_1): borderson(X, c_georegion_l4_x27_y64) = true2.
% 37.90/5.20  The goal is true when:
% 37.90/5.20    X = c_georegion_l4_x27_y65
% 37.90/5.20  
% 37.90/5.20  Proof:
% 37.90/5.20    borderson(c_georegion_l4_x27_y65, c_georegion_l4_x27_y64)
% 37.90/5.20  = { by axiom 5 (ax1_900) R->L }
% 37.90/5.20    fresh93(borderson(c_georegion_l4_x27_y64, c_georegion_l4_x27_y65), true2, c_georegion_l4_x27_y64, c_georegion_l4_x27_y65)
% 37.90/5.20  = { by axiom 3 (ax1_122) R->L }
% 37.90/5.20    fresh93(fresh667(mtvisible(c_tptpgeo_member7_mt), true2), true2, c_georegion_l4_x27_y64, c_georegion_l4_x27_y65)
% 37.90/5.20  = { by axiom 1 (query92) }
% 37.90/5.20    fresh93(fresh667(true2, true2), true2, c_georegion_l4_x27_y64, c_georegion_l4_x27_y65)
% 37.90/5.20  = { by axiom 2 (ax1_122) }
% 37.90/5.20    fresh93(true2, true2, c_georegion_l4_x27_y64, c_georegion_l4_x27_y65)
% 37.90/5.20  = { by axiom 4 (ax1_900) }
% 37.90/5.20    true2
% 37.90/5.20  % SZS output end Proof
% 37.90/5.20  
% 37.90/5.20  RESULT: Theorem (the conjecture is true).
