Here, any seed you care to use gets repeated after exactly one millon generated numbers. No need to store anything but the initial seed. To make sure there are no seeds which result in shorter periods, there are more ellaborated yet still simple algorithms that also don't need storing the whole sequence, see this link, "cycle detection".
