> Is that true? It is not, at least not the way you (and me) are interpreting it. A RNG's period is bounded by the number of states it has, internally[1]: > The period is bounded by the number of the states > If a PRNG's internal state contains n bits, its period can be no longer than 2 ^ n results, and may be much shorter. Our state in the Doom generator is the variable rndindex (or prndindex; we have two generators here); rndindex holds an index in [0, 256) (it is 8 bits), hence we have at most that many states (2 ^ 8, or 256). (I'm assuming the table does not repeat itself, as that would be silly, so in this case, the period is exactly 256 outputs long.)
