% 6.18/6.22  % SZS output start Proof
% 6.18/6.22  The input problem is unsatisfiable because
% 6.18/6.22  
% 6.18/6.22  [1] the following set of Horn clauses is unsatisfiable:
% 6.18/6.22  
% 6.18/6.22  	ifeq(A, A, B, C) = B
% 6.18/6.22  	axiom(or(not(or(A, A)), A)) = true
% 6.18/6.22  	axiom(or(not(A), or(B, A))) = true
% 6.18/6.22  	axiom(or(not(or(A, B)), or(B, A))) = true
% 6.18/6.22  	axiom(or(not(or(A, or(B, C))), or(B, or(A, C)))) = true
% 6.18/6.22  	axiom(or(not(or(not(A), B)), or(not(or(C, A)), or(C, B)))) = true
% 6.18/6.22  	ifeq(axiom(X), true, theorem(X), true) = true
% 6.18/6.22  	ifeq(theorem(Y), true, ifeq(axiom(or(not(Y), X)), true, theorem(X), true), true) = true
% 6.18/6.22  	ifeq(theorem(or(not(Y), Z)), true, ifeq(axiom(or(not(X), Y)), true, theorem(or(not(X), Z)), true), true) = true
% 6.18/6.22  	theorem(or(not(not(p)), or(not(p), q))) = true ==> \bottom
% 6.18/6.22  
% 6.18/6.22  This holds because
% 6.18/6.22  
% 6.18/6.22  [2] the following E entails the following G (Claessen-Smallbone's transformation (2018)):
% 6.18/6.22  
% 6.18/6.22  E:
% 6.18/6.22  	axiom(or(not(A), or(B, A))) = true
% 6.18/6.22  	axiom(or(not(or(A, A)), A)) = true
% 6.18/6.22  	axiom(or(not(or(A, B)), or(B, A))) = true
% 6.18/6.22  	axiom(or(not(or(A, or(B, C))), or(B, or(A, C)))) = true
% 6.18/6.22  	axiom(or(not(or(not(A), B)), or(not(or(C, A)), or(C, B)))) = true
% 6.18/6.22  	f1(theorem(or(not(not(p)), or(not(p), q)))) = true__
% 6.18/6.22  	f1(true) = false__
% 6.18/6.22  	ifeq(A, A, B, C) = B
% 6.18/6.22  	ifeq(axiom(X), true, theorem(X), true) = true
% 6.18/6.22  	ifeq(theorem(Y), true, ifeq(axiom(or(not(Y), X)), true, theorem(X), true), true) = true
% 6.18/6.22  	ifeq(theorem(or(not(Y), Z)), true, ifeq(axiom(or(not(X), Y)), true, theorem(or(not(X), Z)), true), true) = true
% 6.18/6.22  G:
% 6.18/6.22  	true__ = false__
% 6.18/6.22  
% 6.18/6.22  This holds because
% 6.18/6.22  
% 6.18/6.22  [3] E entails the following ordered TRS and the lhs and rhs of G join by the TRS:
