WebNow, concrete answer to your question is that the seed collision probability is AT LEAST equal to MINIMUM of seed space and PRNG period, or in more strict math terms: P <= 1/min (2^seed_bits, PRNG_period) (at least if each seed value maps to different internal state). But as you see, larger period means less independent cycle groups.
