There appears to be no such thing.
"the radius for a selenostationary orbit is much farther than the Hill radius, meaning that no stable orbit can be achieved as it would be too much perturbed by the Earth and/or the Sun"
"all of the Lagrangian points of the Earth-Moon system are stationary relative to the Moon surface"
...but then it is explained that stationary doesn't mean stable.
