Minimal generating systems and properties of Sylow 2-subgroups of alternating group

Publication date: 17 July 2016

Abstract: The background of this paper is the following: search of the minimal systems of generators for this class of group which still was not founded also problem of representation for this class of group, exploration of systems of generators for Sylow 2-subgroups

S y l_{2} A_{2^{k}}

and

S y l_{2} A_{n}

of alternating group, finding structure these subgroups. The aim of this paper is to research the structure of Sylow 2-subgroups and to construct a minimal generating system for such subgroups. In other words, the problem is not simply in the proof of existence of a generating set with elements for Sylow 2-subgroup of alternating group of degree

2^{k}

and its constructive proof and proof its minimality. For the construction of minimal generating set we used the representation of elements of group by automorphisms of portraits for binary tree. The main result is the proof of minimality of this generating set of the above described subgroups and also the description of their structure. Key words: minimal system of generators, wreath product, Sylow subgroups, group, semidirect product.
