% File : SWW430-1 : TPTP v8.2.0. Released v5.2.0.
% Domain : Software Verification
% Problem : Randomly generated entailment of the form F -> \bot (n = 12)
% 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.
