We report the first observation of dijet events with a double
pomeron exchange topology produced in p anti-p collisions at s**(1/2) = 1800
GeV. The events are characterized by a leading antiproton, two jets in the
central pseudorapidity region, and a large rapidity gap on the outgoing
proton side. We present results on jet kinematics and production rates,
compare them with corresponding results from single diffractive and
inclusive dijet production, and test factorization.
