But I managed to do so and created strings with
a length of 16 (6-bit)-characters (a-z, A-Z, 0-9, _, .). Even
14 characters would have been enough.
You need less than twice as many characters for the same effect as in
the 32bit-world.

That's no problem, because the dict doesn't really free a slot, it

These places are later reused for new values or the whole dict is

No, that's not true.
