% Problem  : Entailment for three natural numbers
% Version  : Especial.
% English  : This entailment can be replicated for any three natural numbers
%            i, j, k such that i+j >= k. In this example, they are chosen as
%            2, 3 and 5.

% Comments : Sean Bechhofer says there are some errors in the encoding of
%            datatypes, so this problem may not be perfect. At least it's
%            still representative of the type of reasoning required for OWL.
