“…This result was improved in certain cases by the following result of Perret in [10]: Moreover, Tsfasman [12] and Tsfasman-Vladut [13] [14] obtain asymptotics for the Jacobian; these best known results can also be found in [15]. We recall the following three important theorems contained in this book.…”

“…as Π ranges among all hyperplanes of the space PG( Ω ); we refer to [13] for further details. The codes associated with polar k-Grassmannians of either orthogonal, symplectic or Hermitian type have been introduced respectively in [1], [4] and [5].…”
In this paper we determine the minimum distance of orthogonal line-Grassmann codes for q even. The case q odd was solved in [3]. For n = 3 we also determine the second smallest distance. Furthermore, we show that for q even all minimum weight codewords are equivalent and that symplectic line-Grassmann codes are proper subcodes of codimension 2n of the orthogonal ones.
