Actually, A062163 is a duplicate of (much developed) A002729 with the
only difference that A002729 lacks the 0th term.
Neil, I suggest to prepend the 0th term (equal 1) to A002729 and merge
A062163 to it (moving the current %E field of A062163 to the %C field
of A002729).

be on vacation. What this means:
- continue to send important new sequences and comments
- don't send less important sequences or minor comments
There will still be updates, but not so many.
There is still a large backlog of new seqs and comments
that I am working on.
