=abstract=
In this paper we disprove on of the recent conjectures
of Graffiti, a computer system which makes
graph-theoretical hypotheses. We present an entire
family of counterexamples and, moreover, we describe the
way the counterexamples are derived, which bases both on
the search of large catalogs of structures and on
mathematical understanding and generalization of the
results. Such an approach fits well the area of
experimental mathematics.
