Where does Callisto currently sit relative to the Laplace resonance chain involving Io, Europa, and Ganymede?

Answer

Outside the resonance

Callisto is currently outside the precisely timed orbital resonance shared by the inner three Galilean moons, suggesting it either formed independently or migrated outward and broke free from a previous resonance.
