% 0.13/0.41  The input problem is unsatisfiable because
% 0.13/0.41  
% 0.13/0.41  [1] the following set of Horn clauses is unsatisfiable:
% 0.13/0.41  
% 0.13/0.41  	multiply(identity, X) = X
% 0.13/0.41  	multiply(inverse(X), X) = identity
% 0.13/0.41  	multiply(multiply(X, Y), Z) = multiply(X, multiply(Y, Z))

% 0.13/0.41  	multiply(greatest_lower_bound(Y, Z), X) = greatest_lower_bound(multiply(Y, X), multiply(Z, X))
