Given a graph $G$, we define ${\text{ex}}_c(G)$ to be the minimum value of $t$ for which there exists a constant $N(t,G)$ such that every $t$-connected graph with at least $N(t,G)$ vertices contains $G$ as a minor. The value of ${\text{ex}}_c(G)$ is known to be tied to the vertex cover number $\tau (G)$, and in fact $\tau(G)\leq …
