Abstract

Let Γ(n,k) be the Grassmann graph formed by the k-dimensional subspaces of a vector space of dimension n over a field F and, for t∈N∖{0}, let Δt(n,k) be the subgraph of Γ(n,k) formed by the set of linear [n,k]-codes having minimum dual distance at least t+1. We show that if |F|≥(nt) then Δt(n,k) is connected and it is isometrically embedded in Γ(n,k).
