% 2.39/2.52  % SZS status Unsatisfiable
% 2.39/2.52  % SZS output start Proof
% 2.39/2.52  The input problem is unsatisfiable because
% 2.39/2.52  
% 2.39/2.52  [1] the following set of Horn clauses is unsatisfiable:
% 2.39/2.52  
% 2.39/2.52  	implies(truth, X) = X
% 2.39/2.52  	implies(implies(X, Y), implies(implies(Y, Z), implies(X, Z))) = truth
% 2.39/2.52  	implies(implies(X, Y), Y) = implies(implies(Y, X), X)
% 2.39/2.52  	implies(implies(not(X), not(Y)), implies(Y, X)) = truth
% 2.39/2.52  	implies(x, implies(y, x)) = truth ==> \bottom
% 2.39/2.52  
% 2.39/2.52  This holds because
% 2.39/2.52  
% 2.39/2.52  [2] the following E entails the following G (Claessen-Smallbone's transformation (2018)):
% 2.39/2.52  
% 2.39/2.52  E:
% 2.39/2.52  	f1(implies(x, implies(y, x))) = true__
% 2.39/2.52  	f1(truth) = false__
% 2.39/2.52  	implies(implies(X, Y), Y) = implies(implies(Y, X), X)
% 2.39/2.52  	implies(implies(X, Y), implies(implies(Y, Z), implies(X, Z))) = truth
% 2.39/2.52  	implies(implies(not(X), not(Y)), implies(Y, X)) = truth
% 2.39/2.52  	implies(truth, X) = X
% 2.39/2.52  G:
% 2.39/2.52  	true__ = false__
% 2.39/2.52  
% 2.39/2.52  This holds because
% 2.39/2.52  
% 2.39/2.52  [3] E entails the following ordered TRS and the lhs and rhs of G join by the TRS:
% 2.39/2.52  
% 2.39/2.52  	implies(implies(X, Y), Y) = implies(implies(Y, X), X)
% 2.39/2.52  	f1(implies(x, implies(y, x))) -> true__
% 2.39/2.52  	f1(truth) -> false__
% 2.39/2.52  	implies(Y0, implies(X1, implies(implies(Y0, Y1), Y1))) -> truth
% 2.39/2.52  	implies(Y0, truth) -> truth
% 2.39/2.52  	implies(Y1, Y1) -> truth
% 2.39/2.52  	implies(Y1, implies(Y0, Y1)) -> truth
% 2.39/2.52  	implies(Y1, implies(implies(Y1, Y2), Y2)) -> truth
% 2.39/2.52  	implies(implies(X, Y), implies(implies(Y, Z), implies(X, Z))) -> truth
% 2.39/2.52  	implies(implies(Y0, Y1), implies(Y0, implies(X1, Y1))) -> truth
% 2.39/2.52  	implies(implies(Y0, implies(not(Y2), not(truth))), implies(Y0, Y2)) -> truth
% 2.39/2.52  	implies(implies(Y1, Y2), implies(implies(not(Y1), not(truth)), Y2)) -> truth
% 2.39/2.52  	implies(implies(Y1, implies(not(Y1), not(truth))), implies(not(Y1), not(truth))) -> Y1
% 2.39/2.52  	implies(implies(implies(X1, X0), implies(not(X0), not(X1))), implies(not(X0), not(X1))) -> implies(X1, X0)
% 2.39/2.52  	implies(implies(implies(X1, Y0), Y2), implies(Y0, Y2)) -> truth
% 2.39/2.52  	implies(implies(implies(Y1, X0), X0), Y1) -> implies(X0, Y1)
% 2.39/2.52  	implies(implies(implies(implies(Y0, X1), X1), Y2), implies(Y0, Y2)) -> truth
% 2.39/2.52  	implies(implies(not(X), not(Y)), implies(Y, X)) -> truth
% 2.39/2.52  	implies(implies(not(Y0), not(implies(X0, Y0))), implies(implies(Y0, X0), X0)) -> truth
% 2.39/2.52  	implies(implies(not(Y0), not(truth)), Y0) -> truth
% 2.39/2.52  	implies(implies(not(Y0), not(truth)), implies(X1, Y0)) -> truth
% 2.39/2.52  	implies(implies(not(implies(not(Y1), not(truth))), not(implies(Y1, implies(not(Y1), not(truth))))), Y1) -> truth
% 2.39/2.52  	implies(implies(not(truth), not(not(truth))), not(not(truth))) -> truth
% 2.39/2.52  	implies(not(truth), Y1) -> truth
% 2.39/2.52  	implies(not(truth), not(not(truth))) -> not(not(truth))
% 2.39/2.52  	implies(truth, X) -> X
% 2.39/2.52  	true__ -> false__
% 2.39/2.52  with the LPO induced by
% 2.39/2.52  	y > x > not > implies > truth > f1 > true__ > false__
