Dear SeqFans,

sequence
A088867 : Numbers that can be expressed as the sum of two distinct 4th
powers in exactly two distinct ways that have at least one repeated
factor.

had some issues.
I think I fixed most of them and invite anyone who has some insight
and/or already looked into this to check my draft edits & comments at
https://oeis.org/draft/A088867/.

In particular it had the kw "fini", I think this is incorrect.
(If you can confirm, it should be removed in A88849, too.
If I'm wrong, should it also be added to A3824 ?)

Also, there are 2 links to documents on msnusers.com which seem
broken, and although web.archive lists dates of captures,
http://wayback.archive.org/web/*/http://www.msnusers.com/BC2LCC/*
I only get empty pages when I follow these links.
(This may be an issue of my browser, and/or due to the fact that these
are .txt and not .html files.)

Thanks,

Maximilian
