There are now four sequences:
A279000 and A279001, which Lars Blomberg has corrected, and
A279194 and A279195, which are the sequences J and K on page 10
of the arXiv paper, but whose definitions are not clear to me.

Arie Groeneveld, can you give me definitions for A279194 and A279195?

And what about the earlier sequences that I added: A278996, A278997,
A278998, and A278999. Are they OK?  Now I am worried!
