[seqfan] Re: A039686 vs A147608

[T. D. Noe]

This sequence has been around so long that we should not delete it.  This
policy extends to all sequences that have been in OEIS for a couple of
years.  If a sequence is wrong, just say so and give the number of the
correct sequence.

Best regards,

Tony
