Given the necessary caveats about limitations of PRNGs, the request seems
a reasonable one in context. Since (almost?) every PRNG has a (large) finite
cycle length L, it makes sense to wonder whether, in theory, a generator might
somehow be designed to allow the user to select among the L rotations of the
cycle. In principle, the cycle itself would not need to be known to do this, only
its length. And this wouldn't make the generator any "more rotten" than if its
cycle were not rotation selectable. I don't know if such a generator has ever
been designed, but I believe it is at least possible in theory.
(Of course, theoretically you could store a cycle of values, and then select from
them, but I'm refering to algorithms that don't calculate intermediate values).

The space would consist of ordered pairs of form (x, y)=(x, (1-2x)/3), for all real x.
Consider two arbitrary reals x' and x'', and add the two corresponding would-be
vectors. In a vector space, this sum must also result in an element of the space.
Try it and see ...

| Help with homework (vector spaces):

| The problem is to find out whether a given set is a vector space.
|
| The problem is as follows:
| W' is the set of all ordered pairs(x,y) of real numbers that satisfy the
| equation 2x+3y=1.
|
| The answer at the end of the book says, that this set is not a vector
