Nov 28 at 16:29 comment added Fedor Petrov I mean, join by a common vertex
Nov 28 at 16:25 comment added Connor I think after removing any two vertices of the join, the remaining is still connected? So it is 2-connected?
Nov 28 at 15:11 comment added Fedor Petrov Join $K_{n-1}$ and $K_2$. A separator is large, but it is not even two-connected
