For example, let's say I want two cryptographically strong RNGs (R1 and R2). And I want them to have the following property: R1 (resp. R2) will never generate the same random number twice. R1 (resp. R2) will never generate a random number that R2 (resp. R1) can generate.
Is it possible for three RNGs, 4, N ?
Unlike other questions already on the site, I don't need the generated RNGs to be tracked back to their generator.
