There are precisely 2 such, of course.
Geostationary orbits are unstable because of out of equatorial plane perturbations from Moon and Sun, causing geostationary satellites to leave geostationary orbits and go to inclined geosynchronous orbits, which are 8-shaped orbits around a point of equator.
However, the Laplace plane at geosynchronous distance is at 7,4 degrees from equator, which means that a satellite at geosynchronous orbit of 7,4 degrees in correct direction is stable to that and the inclination will stay constant.
Also, the equator of Earth is not round, which is why there are just 2 points around geosynchronous orbit that are stable in longitude.

However, for those 2 geosynchronous orbits, what is the next order perturbation?
