% 112.87/112.80  % SZS output start Proof
% 112.87/112.80  The input problem is unsatisfiable because
% 112.87/112.80  
% 112.87/112.80  [1] the following set of Horn clauses is unsatisfiable:
% 112.87/112.80  
% 112.87/112.80  	implies(truth, X) = X
% 112.87/112.80  	implies(implies(X, Y), implies(implies(Y, Z), implies(X, Z))) = truth
% 112.87/112.80  	implies(implies(X, Y), Y) = implies(implies(Y, X), X)
% 112.87/112.80  	implies(implies(not(X), not(Y)), implies(Y, X)) = truth
% 112.87/112.80  	or(X, Y) = implies(not(X), Y)
% 112.87/112.80  	or(or(X, Y), Z) = or(X, or(Y, Z))
% 112.87/112.80  	or(X, Y) = or(Y, X)
% 112.87/112.80  	and(X, Y) = not(or(not(X), not(Y)))
% 112.87/112.80  	and(and(X, Y), Z) = and(X, and(Y, Z))
% 112.87/112.80  	and(X, Y) = and(Y, X)
% 112.87/112.80  	xor(X, Y) = or(and(X, not(Y)), and(not(X), Y))
% 112.87/112.80  	xor(X, Y) = xor(Y, X)
% 112.87/112.80  	and_star(X, Y) = not(or(not(X), not(Y)))
% 112.87/112.80  	and_star(and_star(X, Y), Z) = and_star(X, and_star(Y, Z))
% 112.87/112.80  	and_star(X, Y) = and_star(Y, X)
% 112.87/112.80  	not(truth) = falsehood
% 112.87/112.80  	and_star(x, truth) = x ==> \bottom
% 112.87/112.80  
% 112.87/112.80  This holds because
% 112.87/112.80  
% 112.87/112.80  [2] the following E entails the following G (Claessen-Smallbone's transformation (2018)):

% 112.87/112.80  	f1(x) = false__
% 112.87/112.80  	implies(implies(X, Y), Y) = implies(implies(Y, X), X)
