There is a gap in the OEIS where 698 sequence numbers have been skipped
(A181891-A182588) so they never become allocated to anyone.
A182589 is the only dead sequence in the OEIS with nothing in the name
and data fields, and is the only sequence number which is listed in the
gzipped stripped file but not in the gzipped names file.
Consequently, nearby sequences have a large gap in the adjacent
sequences listed in their Cross-refs fields, jumping from A181890 to
There are also many sequence numbers which had been allocated to people
up to a year ago that have never been recycled. These include A173656,
A173718, A173719, A174651, A174849, A178921, A178959, A180058, A181777,
A181783, A181848, A182662-A182668, A182780, A183168, A183188-A183193,
etc. Surely those which have not been edited since they were allocated
more than, say, five or six weeks ago should be recycled, rather than
left unused indefinitely.
