Any symmetric 2-(31,10,3) design gives rise to a binary self-dual doubly-even code of length 64, and the code is extremal if and only if the design does not possess any ovals [15]. Codes derived from the known symmetric 2-(31, 10, 3) designs without ovals and their automorphism groups are investigated. It is shown that the 6 known such designs lead to 4 inequivalent extremal codes, one code having full automorphism group of order 2.
