It is proved that a finite group that is isomorphic to a simple non-Abelian group $G=G_2(3^n)$ is, up to isomorphism, recognized by a set $\omega(G)$ of its element orders, that is, $H \simeq G$ if $\omega(H)=\omega(G)$ for some finite group $H$.
Keywords: finite group, recognizability of groups by their element orders.
Mots-clés : simple non-Abelian group
