% 5.65/5.68  % SZS output start Proof
% 5.65/5.68  The input problem is unsatisfiable because
% 5.65/5.68  
% 5.65/5.68  [1] the following set of Horn clauses is unsatisfiable:
% 5.65/5.68  
% 5.65/5.68  	product(identity, X, X)
% 5.65/5.68  	product(X, identity, X)
% 5.65/5.68  	product(X, Y, U) & product(Y, Z, V) & product(U, Z, W) ==> product(X, V, W)
% 5.65/5.68  	product(X, Y, U) & product(Y, Z, V) & product(X, V, W) ==> product(U, Z, W)
% 5.65/5.68  	product(X, X, identity)
% 5.65/5.68  	product(a, b, c)
% 5.65/5.68  	product(b, a, c) ==> \bottom
% 5.65/5.68  
% 5.65/5.68  This holds because
% 5.65/5.68  
% 5.65/5.68  [2] the following E entails the following G (Claessen-Smallbone's transformation (2018)):
% 5.65/5.68  
% 5.65/5.68  E:
% 5.65/5.68  	f1(true__, X, V, W) = product(X, V, W)
% 5.65/5.68  	f2(true__, X, Y, U, V, W) = f1(product(X, Y, U), X, V, W)
% 5.65/5.68  	f3(product(U, Z, W), Y, Z, V, X, U, W) = true__
% 5.65/5.68  	f3(true__, Y, Z, V, X, U, W) = f2(product(Y, Z, V), X, Y, U, V, W)
% 5.65/5.68  	f4(true__, U, Z, W) = product(U, Z, W)
% 5.65/5.68  	f5(true__, X, Y, U, Z, W) = f4(product(X, Y, U), U, Z, W)
% 5.65/5.68  	f6(product(X, V, W), Y, Z, V, X, U, W) = true__

% 5.65/5.68  	product(identity, X, X) = true__
% 5.65/5.68  G:
% 5.65/5.68  	true__ = false__
% 5.65/5.68  
% 5.65/5.68  This holds because
% 5.65/5.68  
% 5.65/5.68  [3] E entails the following ordered TRS and the lhs and rhs of G join by the TRS:
