I remember reading somehwere about the optimal size for human groups to be efficient, but I can't recall the source. If anyone has any pointers, I'd appreciate it!

Efficient at what exactly? Doing a simple task? Complex task? Living as a self-sufficient community?

There have to be different numbers for different problems.

I think it was about the group being able to communicate effectively, to decrease conflict and coordination cost.
