Rigid local systems with monodromy group the Conway group Co2

    We first develop some basic facts about hypergeometric sheaves on the multiplicative group 𝔾m in characteristic p>0. Certain of their Kummer pullbacks extend to irreducible local systems on the affine line in characteristic p>0. One of these, of rank 23 in characteristic p=3, turns out to have the Conway group Co2, in its irreducible orthogonal representation of degree 23, as its arithmetic and geometric monodromy groups.
