    En el presente artículo se muestran algunas técnicas para obtener tipos de automorfismos de los códigos binarios auto-duales, doblemente pares y extremales, también denominados extremales de tipo II, con parámetros [24, 12, 8], [48, 24, 12] y [120, 60, 24]. El objetivo central es obtener información sobre el correspondiente grupo de automorfismos a partir de la exclusión de algunos números primos de su orden.

    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.
