% 7.91/7.97  % SZS status Unsatisfiable
% 7.91/7.97  % SZS output start Proof
% 7.91/7.97  The input problem is unsatisfiable because
% 7.91/7.97  
% 7.91/7.97  [1] the following set of Horn clauses is unsatisfiable:
% 7.91/7.97  
% 7.91/7.97  	implies(truth, X) = X
% 7.91/7.97  	implies(implies(X, Y), implies(implies(Y, Z), implies(X, Z))) = truth
% 7.91/7.97  	implies(implies(X, Y), Y) = implies(implies(Y, X), X)
% 7.91/7.97  	implies(implies(not(X), not(Y)), implies(Y, X)) = truth
% 7.91/7.97  	implies(implies(x, y), implies(not(y), not(x))) = truth ==> \bottom
% 7.91/7.97  
% 7.91/7.97  This holds because
% 7.91/7.97  
% 7.91/7.97  [2] the following E entails the following G (Claessen-Smallbone's transformation (2018)):
% 7.91/7.97  
% 7.91/7.97  E:
% 7.91/7.97  	f1(implies(implies(x, y), implies(not(y), not(x)))) = true__
% 7.91/7.97  	f1(truth) = false__
% 7.91/7.97  	implies(implies(X, Y), Y) = implies(implies(Y, X), X)
% 7.91/7.97  	implies(implies(X, Y), implies(implies(Y, Z), implies(X, Z))) = truth
% 7.91/7.97  	implies(implies(not(X), not(Y)), implies(Y, X)) = truth
% 7.91/7.97  	implies(truth, X) = X
% 7.91/7.97  G:
% 7.91/7.97  	true__ = false__
% 7.91/7.97  
% 7.91/7.97  This holds because
% 7.91/7.97  
% 7.91/7.97  [3] E entails the following ordered TRS and the lhs and rhs of G join by the TRS:
% 7.91/7.97  
% 7.91/7.97  	implies(implies(X, Y), Y) = implies(implies(Y, X), X)

% 7.91/7.97  	not(X0) = implies(X0, not(truth))
% 7.91/7.97  	f1(implies(implies(x, y), implies(not(y), not(x)))) -> true__
