We survey three aspects of the dependence of the connective constant on the underlying graph $G$. Firstly, when $G$ is cubic, we study the effect on $\\mu(G)$ of the Fisher transformation (that is, the replacement of vertices by triangles). Secondly, we discuss upper and lower bounds for $\\mu(G)$ when $G$ is regular. Thirdly, we present strict inequalities for the connective constants $\\mu(G)$ of vertex-transitive graphs $G$, as $G$ varies.
