Abstract:
Let $G$ be a periodic group, and let $\omega(G) \subseteq {\Bbb N}$ be the spectrum of $G$
that is the set of orders of elements in $G$.
We prove that the alternating group $A_{7}$ is uniquely recognized by its spectrum in the class of all groups.
Keywords:
periodic group, locally finite group, spectrum.
