There are apparently two sets of seqs using this construction,
found as



IMO these are noise and should be deleted.

@Neil: if the only reference to any of those seqs
are from any of those seqs it would be safe to delete them
(yes, I have read your other mail).

Note that seqs like A138068 and A138069 are those generating
useless hits with searches.  This happens to me if I search
for a (hard-won) short seq of small numbers.  It strikes
me that the most effective way to narrow down such searches
is to exclude certain authors contained in a rather small set.
