Abstract:
The spectrum of a group is the set of its element orders. A finite group $G$ is said to be recognizable by spectrum if every finite group with the same spectrum is isomorphic to $G$. We prove that if $n\in\{15,16,18,21,27\}$ then symmetric groups $Sym_n$ are recognizable by spectrum.
Keywords:
finite group, simple group, symmetric group, spectrum of a group, recognizability by spectrum.
