COMMENTS
| Presumably this triangle will differ from that in A130791 after some point. - N. J. A. Sloane (njas(AT)research.att.com), Sep 22 2007
Apart from the initial term, this sequence coincides with A130791 for at least the first 210 rows. - David W. Wilson (davidwwilson(AT)comcast.net), Sep 22 2007
