  "abstract": "We give a complete classification of the automorphisms of twisted Chevalley groups of types ${}^2A_3$ and ${}^2A_4$, and of their elementary subgroups, over commutative local rings $R$ containing $1/2$ and equipped with a non-trivial involution $θ$. The classification covers all isogeny types and, together with our higher-rank result~\\cite{EB&DM1}, completes the description for type ${}^2A_{\\ell}$ with $\\ell\\geq3$.",
