Eleventh International Workshop on Algebraic and Combinatorial Coding Theory

Abstract. The existences of an extremal doubly even self-dual [96, 48, 20] code and a self-dual [94, 47, 18] code are equivalent. The largest minimum weight among self-dual codes of length 94 was previously known as 14, 16 or 18. In this note, a self-dual [94, 47, 16] code is constructed for the first time.
