in 2009, Jonathan Wellons defined 336 OEIS sequences in the range
A136808 - A137146. They are based on the decimal digits, but more
interesting as it might seem at first sight. Some are perhaps finite,
some seem to be hard. For some patterns a proof is outstanding.
I think that some could have a connection to cellular automata.
The sequences link to Jonathan's homepage, but jonathanwellons.com
is no longer accessible. I wrote an email to the address cited on his
archived pages, but without reply (so far).
If have restored the page, and I have some ideas for the proofs,
so if anybody of you finds the time, he could look at
for the details.
I think that the links should be repaired in one batch run,
but before, I would need some advice and help from the editors:
What information should be included in the overview page to
