% Problem  : Randomly generated entailment of the form F -> \bot (n = 17)
% Version  : Especial.
% English  : A randomly generated entailment with n program variables.
%            Negated equalities and list segments are added at random, with
%            specific paramenters so that about half of the generated
%            entailments are valid (or, equivalently, F is unsatisfiable).
%            Normalization and well-formedness axioms should be enough to
%            decide these entailments.
