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.

Does that also effect the Lagrange points for the moon? Do human currently have anything parked at earth moon lagrange points?
