Query: Velocity Memory Effect for Polarized Gravitational Waves   Circularly polarized gravitational sandwich waves exhibit, as do their
linearly polarized counterparts, the Velocity Memory Effect: freely falling
test particles in the flat after-zone fly apart along straight lines with
constant velocity. In the inside zone their trajectories combine oscillatory
and rotational motions in a complicated way. For circularly polarized periodic
gravitational waves some trajectories remain bounded, while others spiral
outward. These waves admit an additional "screw" isometry beyond the usual
five. The consequences of this extra symmetry are explored.
