% 0.24/0.64 fof(p47_52, negated_conjecture, ![X151, X152, X153, X154]: (p47(X151, X152) | (~p47(X153, X154) | (~p7(X154, X152) | ~p4(X153, X151))))).

% 0.24/0.64 fof(p47_76, negated_conjecture, p47(f5(c48, f8(f10(c49, f13(f16(f18(c50, c51), c52), c53)), c54)), c54)).

% 0.24/0.65
% 0.24/0.65 Now clausify the problem and encode Horn clauses using encoding 3 of
% 0.24/0.65 http://www.cse.chalmers.se/~nicsma/papers/horn.pdf.
% 0.24/0.65 We repeatedly replace C & s=t => u=v by the two clauses:
% 0.24/0.65 fresh(y, y, x1...xn) = u
% 0.24/0.65 C => fresh(s, t, x1...xn) = v
% 0.24/0.65 where fresh is a fresh function symbol and x1..xn are the free
% 0.24/0.65 variables of u and v.
% 0.24/0.65 A predicate p(X) is encoded as p(X)=true (this is sound, because the
% 0.24/0.65 input problem has no model of domain size 1).
% 0.24/0.65
% 0.24/0.65 The encoding turns the above axioms into the following unit equations and goals:
% 0.24/0.65
% 0.24/0.65 Axiom 1 (p7_3): p7(X, X) = true2.
% 0.24/0.65 Axiom 2 (p2_20): p2(X, X) = true2.
% 0.24/0.65 Axiom 3 (p47_52): fresh98(X, X, Y, Z) = true2.
% 0.24/0.65 Axiom 4 (p47_73): fresh17(X, X, Y, Z) = true2.
% 0.24/0.65 Axiom 5 (p47_52): fresh18(X, X, Y, Z, W) = p47(Y, Z).
% 0.24/0.65 Axiom 6 (p47_52): fresh97(X, X, Y, Z, W, V) = fresh98(p7(V, Z), true2, Y, Z).
% 0.24/0.65 Axiom 7 (p4_57): fresh12(X, X, Y, Z, W, V) = p4(f5(Y, Z), f5(W, V)).
% 0.24/0.65 Axiom 8 (p4_57): fresh11(X, X, Y, Z, W, V) = true2.
% 0.24/0.65 Axiom 9 (p47_52): fresh97(p47(X, Y), true2, Z, W, X, Y) = fresh18(p4(X, Z), true2, Z, W, Y).
% 0.24/0.65 Axiom 10 (p4_57): fresh12(p2(X, Y), true2, X, Z, Y, W) = fresh11(p3(Z, W), true2, X, Z, Y, W).
% 0.24/0.65 Axiom 11 (p47_76): p47(f5(c48, f8(f10(c49, f13(f16(f18(c50, c51), c52), c53)), c54)), c54) = true2.
% 0.24/0.65 Axiom 12 (p47_73): fresh17(p47(f5(c48, f13(f16(f18(c50, X), Y), Z)), W), true2, X, W) = p47(X, W).
% 0.24/0.65 Axiom 13 (p3_79): p3(f8(f10(c49, f13(f16(f18(c50, X), Y), Z)), W), f13(f16(f18(c50, f20(f22(f24(f26(c55, X), Y), Z), W)), f30(f32(f34(f36(c56, X), Y), Z), W)), f40(f42(f44(f46(c57, X), Y), Z), W))) = true2.
% 0.24/0.65
% 0.24/0.65 Goal 1 (not_p47_51): p47(f20(f22(f24(f26(c55, X), Y), Z), W), W) = true2.
% 0.24/0.65 The goal is true when:
% 0.24/0.65 X = c51
% 0.24/0.65 Y = c52
% 0.24/0.65 Z = c53
% 0.24/0.65 W = c54
