[seqfan] Sleuthing for xrefs

[Charles Greathouse]

I was looking at cross-references of some sequences recently and I noticed
that there are several dozen with invalid A-numbers there. I was able to
fix many of them but there are some which are obscure. Any ideas about
these?

A001936, A198680, A217099, A219332/A219333, A258279, A058095.

(There are more which remain, but these are the ones I looked at
unsuccessfully.)
