    abstract     = {Summary: Let $G$ be a finite group and $\Gamma (G)$ be the prime graph of $G$. We determine the finite group $G$ such that $\Gamma (G)=\Gamma (L_{22} (2))$ and prove that if $\Gamma (G)=\Gamma (L_{22} (2))$, then $G/O_2 (G)\cong L_{22} (2)$, that is, $L_{22} (2)$ is quasirecognizable. As a corollary, we prove that $L_{22} (2)$ is recognizable by its spectrum.},
