Some self-orthogonal codes related to Higman's Geometry
(Electronic Journal of Combinatorics, 2016)We examine some self-orthogonal codes constructed from a rank-5 primitive permutation representation of degree 1100 of the sporadic simple group HS of Higman-Sims. We show that Aut(C)=HS:2, where C is a code of dimension ...
