Thank you for explaining that, Max.
So what happened was that I got dyslexic about what I was trying to
calculate, and I was extremely surprised that such an obvious sequence was
not in the OEIS. The sequence that I was thinking about has indeed been in
the OEIS almost from the beginning. I have no basis to add the
miscalculated sequence.
