By "a short sequence of 128 values" you mean it repeats itself after
128 values?
I should not write these things when I'm busy and/or especially tired. You're right, I managed to confuse myself.
It's a linear sequence, but not one so short, it's length is 2**128 - 1. The values generated are an exclusive-or of a subset of the last 128 bits generated.
