摘要:

基于对对称密码学的最初兴趣,在本工作中我们研究了一系列子群。从AGL(2,n)的Sylow $2$ -子群开始,链的每一项被定义为$2^n$字母上的对称群中前一项的正规化子。部分结果和计算实验使我们猜想,对于大值的$n$,在连续的一个正规化的指数不依赖于$n$。事实上,有一个强有力的证据表明,该序列的矩阵的指数是一个部分和的数目分区到至少两个不同的部分。

英文摘要:

On the basis of an initial interest in symmetric cryptography, in the present work we study a chain of subgroups. Starting from a Sylow $2$-subgroup of AGL(2,n), each term of the chain is defined as the normalizer of the previous one in the symmetric group on $2^n$ letters. Partial results and computational experiments lead us to conjecture that, for large values of $n$, the index of a normalizer in the consecutive one does not depend on $n$. Indeed, there is a strong evidence that the sequence of the logarithms of such indices is the one of the partial sums of the numbers of partitions into at least two distinct parts.
