Question How do I know the event random numbers are not repeated?

If the random numbers of events are repeated, does Geant4 report error? In addition, if I run 1e10 histories by the following method /run/beamOn 2000000000 /run/beamOn 2000000000 /run/beamOn 2000000000 /run/beamOn 2000000000 /run/beamOn 2000000000 How do I know whether the runs have repeated events or not? I need 1e10 independent events, but the statistical behaviors of 2e9 events and 1e10 events look no difference (I dumped scored results after each run and added them up in Matlab code). Any advice is greatly appreciated.
