  Lorenz equations were first presented in 1963 by Edward Lorenz, they depend
on three real positive parameters. For some of these parameters which are
called T-points, there are two heteroclinic orbits connecting the three
singular points in the equations. The heteroclinic connections can be extended
into an invariant curve passing through infinity. We consider the system at the
second T-point parameter, and develop a geometric model for the flow that
simulates the Lorenz dynamics there. We show that the model contains infinitely
many periodic orbits, and that as knots they are all positive, prime and
fibered.
