Abstract

It is shown that the minimal distance d of a singly-even self-dual [24t+8, 12t+4] code is at most 4t+2 if its shadow contains a weight 4 vector, t is even, and (t5t) is odd. It is proved particularly that there does not exist a singly-even self-dual code with 4862 words of weight 12. This answers a question of Conway and Sloane raised in their joint paper in 1990.
