  We discuss USp(2n) supersymmetric models with eight fundamental fields and a
field in the antisymmetric representation. Turning on the most generic
superpotentials, coupling pairs of fundamental fields to powers of the
antisymmetric field while preserving an R symmetry, we give evidence for the
statement that the models are connected by a large network of dualities which
can be organized into orbits of the Weyl group of E_8. We make also several
curious observations about such models. In particular, we argue that a USp(2m)
model with the addition of singlet fields and even rank m flows in the IR to a
CFT with E_7 U(1) symmetry. We also discuss an infinite number of duals for the
USp(2) theory with eight fundamentals and no superpotential.
