On periodic groups isospectral to $a_7$
A. S. Mamontov Sobolev Institute of Mathematics, Siberian Branch of the Russian Academy of Sciences, Novosibirsk
Abstract:
Let $A_n$ denote the alternating group of degree $n$. Consider a group $G$ whose spectrum, i.e. the set of element orders, equals the spectrum of $A_7$. Assume that $G$ has a subgroup $H$ isomorphic to $A_4$ whose involutions are squares of elements of order $4$. Then either $O_2(H) \subseteq O_2(G)$ or $G$ has a nonabelian finite simple subgroup.
Keywords:
periodic group, locally finite group.
