| Aug 8, 2023 at 15:31 | comment | added | Marco Ripà | A000978 is the main sequence, but since the question was not very clear to me, I decided to add some other related info (i.e., by providing that link which includes A361562, A361563, etc...). It all depends on what set of rules @Twiga is really looking for. | |
