 There is no limit to the number of seeds. If you want to use a thousand seeds, you can. The method functions fine with that. In that case it would be more efficient to put the seeds in a table and read and write to the table with two pointers. But it is hard to imagine a use-case where there is a need for more than 256 bits of seeds, so for instance eight 32 bit seeds. This gives a wrap-to-zero period of 2<sup>256</sup>-1. Even if you generate 1 bilion values per second, the universe would cease to exist before the generator wraps to the start. There is no limit to the number of seeds.
