[seqfan] Re: Another planetary sequence

[Neil Sloane]

my personal feeling is that that planetary sequence isn't quite interesting
enough
for an OEIS entry.  The terms are not integers, and they are certainly
time-dependent.
Of course the OEIS may not be around in a billion years, but still!

Best regards
Neil
