Best Linear Codes

Based on an method first described in a series of papers by Michael Braun, Axel Kohnert, Alfred Wassermann (see [1],[2] ) we constructed a large number of linear codes with prescribed minimum distance. A generator matrix of each constructed code was stored in a database.To solve the corresponding Diophantine linear systems we also used sometimes a special programm developed by Johannes Zwanzger [3]. The following links allow to access this database for the listed combinations of field size q and dimension k.
