Let E be a non CM elliptic curve defined over $\Q$. There is an isogeny torsion graph associated to E and there is also a Galois representation $\rho_E : Gal(\Qbar/\Q) \to \GL_2(\Z_l)$ associated to E for every prime l. In this talk, I will discuss a classification of 3 adic Galois images associated to vertices of isogeny torsion graph of E.
