Looking for a specific integer sequence, but OEIS search is failing...

"Number of possible directed graphs with 'n' nodes"

I think it's 1, 6, and uhhh... I lost count after that.

@cr1901 if the nodes are interchangeable then https://oeis.org/A000273
A000273 - OEIS

@alexing According to past-me, nodes were not interchangeable: https://mastodon.social/@cr1901/116302086631790379

But good to know :D!
