The Expurgation-Augmentation Method for Constructing Good Plane Subspace Codes


As shown in [31], one of the five isomorphism types of optimal binary subspace codes of size 77 for packet length v = 6, constant dimension k = 3 and minimum subspace distance d = 4 can be constructed by first expurgating and then augmenting the corresponding lifted Gabidulin code in a fairly simple way. The method was refined in [36, 29] to yield an… (More)
