% 11.30/1.84 % SZS output start Proof
% 11.30/1.84 Take the following subset of the input axioms:
% 11.30/1.84 fof(exemplo6GDDFULL214028, conjecture, ![A, B, C, F, P, Q, H, T]: ((perp(F, C, A, B) & (coll(F, A, B) & (perp(B, C, A, H) & (perp(A, C, B, H) & (perp(T, F, B, C) & (coll(T, B, C) & (perp(Q, F, A, H) & (coll(Q, A, H) & (perp(P, F, A, C) & coll(P, A, C)))))))))) => coll(P, Q, T))).
% 11.30/1.84 fof(ruleD1, axiom, ![A2, B2, C2]: (coll(A2, B2, C2) => coll(A2, C2, B2))).
% 11.30/1.84 fof(ruleD19, axiom, ![D, U, V, B2, C2, A2_2, P2, Q2]: (eqangle(A2_2, B2, C2, D, P2, Q2, U, V) => eqangle(C2, D, A2_2, B2, U, V, P2, Q2))).
% 11.30/1.84 fof(ruleD2, axiom, ![B2, C2, A2_2]: (coll(A2_2, B2, C2) => coll(B2, A2_2, C2))).
% 11.30/1.84 fof(ruleD3, axiom, ![B2, C2, D2, A2_2]: ((coll(A2_2, B2, C2) & coll(A2_2, B2, D2)) => coll(C2, D2, A2_2))).
% 11.30/1.84 fof(ruleD39, axiom, ![B2, C2, D2, A2_2, P2, Q2]: (eqangle(A2_2, B2, P2, Q2, C2, D2, P2, Q2) => para(A2_2, B2, C2, D2))).
% 11.30/1.84 fof(ruleD40, axiom, ![B2, C2, D2, A2_2, P2, Q2]: (para(A2_2, B2, C2, D2) => eqangle(A2_2, B2, P2, Q2, C2, D2, P2, Q2))).
% 11.30/1.84 fof(ruleD66, axiom, ![B2, C2, A2_2]: (para(A2_2, B2, A2_2, C2) => coll(A2_2, B2, C2))).
% 11.30/1.84 fof(ruleD8, axiom, ![B2, C2, D2, A2_2]: (perp(A2_2, B2, C2, D2) => perp(C2, D2, A2_2, B2))).
% 11.30/1.84 fof(ruleD9, axiom, ![E, B2, C2, D2, F2, A2_2]: ((perp(A2_2, B2, C2, D2) & perp(C2, D2, E, F2)) => para(A2_2, B2, E, F2))).
% 11.30/1.84
% 11.30/1.84 Now clausify the problem and encode Horn clauses using encoding 3 of
% 11.30/1.84 http://www.cse.chalmers.se/~nicsma/papers/horn.pdf.
% 11.30/1.84 We repeatedly replace C & s=t => u=v by the two clauses:
% 11.30/1.84 fresh(y, y, x1...xn) = u
% 11.30/1.84 C => fresh(s, t, x1...xn) = v
% 11.30/1.84 where fresh is a fresh function symbol and x1..xn are the free
% 11.30/1.84 variables of u and v.
% 11.30/1.84 A predicate p(X) is encoded as p(X)=true (this is sound, because the
% 11.30/1.84 input problem has no model of domain size 1).
% 11.30/1.84
% 11.30/1.84 The encoding turns the above axioms into the following unit equations and goals:
% 11.30/1.84
% 11.30/1.84 Axiom 1 (exemplo6GDDFULL214028_6): perp(q, f, a, h) = true.
% 11.30/1.84 Axiom 2 (ruleD1): fresh146(X, X, Y, Z, W) = true.
% 11.30/1.84 Axiom 3 (ruleD2): fresh133(X, X, Y, Z, W) = true.
% 11.30/1.84 Axiom 4 (ruleD3): fresh119(X, X, Y, Z, W) = true.
% 11.30/1.84 Axiom 5 (ruleD66): fresh66(X, X, Y, Z, W) = true.

% 11.30/1.84 Axiom 7 (ruleD39): fresh106(X, X, Y, Z, W, V) = true.
% 11.30/1.84 Axiom 8 (ruleD8): fresh52(X, X, Y, Z, W, V) = true.
% 11.30/1.84 Axiom 9 (ruleD9): fresh50(X, X, Y, Z, W, V) = true.
% 11.30/1.84 Axiom 10 (ruleD1): fresh146(coll(X, Y, Z), true, X, Y, Z) = coll(X, Z, Y).
% 11.30/1.84 Axiom 11 (ruleD2): fresh133(coll(X, Y, Z), true, X, Y, Z) = coll(Y, X, Z).
% 11.30/1.84 Axiom 12 (ruleD40): fresh104(X, X, Y, Z, W, V, U, T) = true.
% 11.30/1.84 Axiom 13 (ruleD9): fresh51(X, X, Y, Z, W, V, U, T) = para(Y, Z, U, T).
% 11.30/1.84 Axiom 14 (ruleD3): fresh120(coll(X, Y, Z), true, X, Y, W, Z) = fresh119(coll(X, Y, W), true, X, W, Z).
% 11.30/1.84 Axiom 15 (ruleD66): fresh66(para(X, Y, X, Z), true, X, Y, Z) = coll(X, Y, Z).
% 11.30/1.84 Axiom 16 (ruleD19): fresh134(X, X, Y, Z, W, V, U, T, S, X2) = true.
% 11.30/1.84 Axiom 17 (ruleD8): fresh52(perp(X, Y, Z, W), true, X, Y, Z, W) = perp(Z, W, X, Y).
% 11.30/1.84 Axiom 18 (ruleD40): fresh104(para(X, Y, Z, W), true, X, Y, Z, W, V, U) = eqangle(X, Y, V, U, Z, W, V, U).
% 11.30/1.84 Axiom 19 (ruleD9): fresh51(perp(X, Y, Z, W), true, V, U, X, Y, Z, W) = fresh50(perp(V, U, X, Y), true, V, U, Z, W).
% 11.30/1.84 Axiom 20 (ruleD39): fresh106(eqangle(X, Y, Z, W, V, U, Z, W), true, X, Y, V, U) = para(X, Y, V, U).
% 11.30/1.84 Axiom 21 (ruleD19): fresh134(eqangle(X, Y, Z, W, V, U, T, S), true, X, Y, Z, W, V, U, T, S) = eqangle(Z, W, X, Y, T, S, V, U).
