ab: Summary: Using an analysis of the clique structure and only the most
    elementary group theory, we determine the automorphism group of the
    Johnson graph $J(n,i)$, for $n\neq 2i$. Although this is a special case
    of results of {\it G. Jones} [Eur. J. Comb. 26, No. 3‒4, 417‒435
    (2005; Zbl 1063.05037)], unlike his proof, ours uses no heavy
    group-theoretic machinery. We make a conjecture for the case $n=2i$.
