% 0.13/0.39  % SZS output start Proof
% 0.13/0.39  The input problem is unsatisfiable because
% 0.13/0.39  
% 0.13/0.39  [1] the following set of Horn clauses is unsatisfiable:
% 0.13/0.39  
% 0.13/0.39  	meet(X, join(X, Y)) = X
% 0.13/0.39  	join(X, meet(X, Y)) = X
% 0.13/0.39  	meet(X, Y) = meet(Y, X)
% 0.13/0.39  	join(X, Y) = join(Y, X)
% 0.13/0.39  	meet(meet(X, Y), Z) = meet(X, meet(Y, Z))
% 0.13/0.39  	join(join(X, Y), Z) = join(X, join(Y, Z))
% 0.13/0.39  	join(xx, xx) = xx ==> \bottom
% 0.13/0.39  
% 0.13/0.39  This holds because
% 0.13/0.39  
% 0.13/0.39  [2] the following E entails the following G (Claessen-Smallbone's transformation (2018)):
% 0.13/0.39  
% 0.13/0.39  E:
% 0.13/0.39  	f1(join(xx, xx)) = true__
% 0.13/0.39  	f1(xx) = false__
% 0.13/0.39  	join(X, Y) = join(Y, X)

% 0.13/0.39  	true__ = false__
% 0.13/0.39  
% 0.13/0.39  This holds because

% 0.13/0.39  [3] E entails the following ordered TRS and the lhs and rhs of G join by the TRS:

% 0.13/0.39  	meet(Y1, meet(Y0, Y2)) = meet(Y0, meet(Y1, Y2))
% 0.13/0.39  	meet(Y2, meet(Y0, Y1)) = meet(Y0, meet(Y1, Y2))
