GUTIERREZ GARCIA, ISMAEL  and  VILLAR SALINAS, DARWIN. On authomorphisms of extremal type II codes. Integración - UIS [online]. 2013, vol.31, n.2, pp.107-120. ISSN 0120-419X.

In this article we present some techniques to determine the types of automorphisms of extremal doubly even binary self-dual codes, also called extremal type II codes, with parameters [24, 12, 8], [48, 24, 12] and [120, 60, 24]. We aim to obtain information about the automorphism group considering the exclusion of some prime numbers from its order

Keywords : Binary codes; self-dual codes; doubly even codes; extremal codes and automorphisms of codes.
