The Bulgarian annual National Seminar on Coding Theory was founded in 1988 by Prof. Stefan Dodunekov who
was his head by the end of his life (2012). The seminar continues to take place every year
and has become the largest national forum on error-correcting codes and related combinatorial tasks.
This web-page contains some of the computational results obtained by participants in the Coding Theory Seminar or by participants in the seminar and their co-authors from all over the world. The collection includes classification results, objects with definite properties, particular examples and bounds on various extremal or optimal combinatorial objects, such as different types of codes (Griesmer, selfdual, doubleweight, optical orthogonal, CRC, covering), incidence structures with specific properties, cryptographic primitives (optimal S-boxes), etc. Access to part of the developed software is also possible. It can be used to obtain new results. Other information related to the results can be found too.
