As far as i know, it was typically around 100 - 120 people and before i knew that i read somewhere that around 100 is the number of relationships the brain can handle.
It’s a fairly nebulous number, it’s going to be different for each individual, and Dunbar was only positing an approximate relationship between brain size and group size. Even if humans can manage 150 or more relationships, it makes sense to keep your group smaller than that to allow for external relationships too.
