    • ...For there is up to equivalence exactly one such code, namely the binary extended Golay code ([15], Theorem 5). Its automorphism group is the Mathieu group ([13], Ch. 20, Corollary 5). For there is again up to equivalence exactly one code, the so-called binary extended quadratic residue code [8]...
