Dear David, and all other members.

The archive system of the seqfan mailing list has long been more and more
(around May 2018 as David writes).  There was a series of unfortunate bugs
the OS, python, mailman, pipermail, language settings, etc. who corrupted
files and skipped many messages.

I don't want to enter into the technical details but one of the challenge
of fixing it is that there many links on the web pointing to this archive
and that most
easy fixes would have broken all these links.

The system has been fixed now for a few weeks on a backup server and I have
to use January 2020 and these recent requests as a launch point.

All mail archive prior to July 1st 2018 are from the ancien system and will

Unfortunately, all links copied in the OEIS  and other web pages pointing
to the archive
for mail posted between August 1st 2018 and today January 15th 2020 will
almost certainly be broken
and must be corrected because the numbering is different.

YOU MAY NEED TO RELOAD PAGES with your browser to see changes.

I am sorry for the inconvenience. The time needed to fix all the
consequences of the
bug was very long on an old and unsupported server.

I will happily help anyone about this topic.
Please post PRIVATELY to me, not to the list for any specific request.
