自对偶[72,36,16]码的自同构群不含S_3,A_4或D_8

The automorphism group of a self-dual [72,36,16] code does not contain S_3, A_4, or D_8

Martino Borello, Francesca Dalla Volta, Gabriele Nebe

摘要:

用Magma进行的计算机计算表明,不存在长度为72的极值自对偶二元码C,其自同构群包含3次对称群、4次交错群或8次二面体群。结合文献中已知的结果,得到Aut(C)的阶数至多为5或同构于阶数为8的初等阿贝尔群。

英文摘要:

A computer calculation with Magma shows that there is no extremal self-dual binary code C of length 72, whose automorphism group contains the symmetric group of degree 3, the alternating group of degree 4 or the dihedral group of order 8. Combining this with the known results in the literature one obtains that Aut(C) has order at most 5 or isomorphic to the elementary abelian group of order 8.
