Where can I find terms 14-21? I tried OEIS, but it only has 1-13, and The Prime Pages only have 22 and 23. FactorDB doesn't have them either, as far as I know.

See post #9?

It has both: 1) all terms ("giving a man a fish"), and 2) advise to register for OEIS Wiki ("teach a man to fish").

I would be grateful if someone could check these to make sure I haven't made any (more) stupid mistakes. I'll proceed with the computation of the next few terms, but it might take a while since I have a few other projects going.
