Yes indeed! Thanks for catching this.
Max A. has removed the terms beyond the last known term (and I made a few
more edits). This has keyword base because it depends on the
the numbers in base 2.
At present there is no escape clause in the definition to say what to do if
such k exists. This is OK, I think, because by the usual heuristic argument
using the prime number theorem, k *should* always exist.
