Abstract: We show that the homotopy class of a quasiconformal self-map of the universal hyperbolic solenoid $ H_\infty$ is the same as its isotopy class and that the uniform convergence of quasiconformal self-maps of $ H_\infty$ to the identity forces them to be homotopic to conformal maps. We identify a dense subset of $ \mathcal{T}(H_\infty )$ such that the orbit under the base leaf preserving mapping class group $ MCG_{BLP}(H_\infty)$ of any point in this subset has accumulation points in the Teichmüller space $ \mathcal{T}(H_\infty )$. Moreover, we show that finite subgroups of $ MCG_{BLP}(H_\infty )$ are necessarily cyclic and that each point of $ \mathcal{T}(H_\infty)$ has an infinite isotropy subgroup in $ MCG_{BLP}(H_\infty )$.
