Most of these concern Chevalley groups, a topic I imagine not many are
familiar with (I certainly am not).

In the specific case of A004217 <https://oeis.org/A004217>, maybe we could
add a file with the 617 digits of a(5). And in the case of
A133026<https://oeis.org/A133026>,
I kind of think both keywords are justified.
