On recognition of simple classical groups with prime graph independence number $4$ by spectrum

Maria A. Grechkoseeva, Vladislav M. Rodionov

Let $L$ be one of the finite simple classical groups $L_8(q)$, $U_8(q)$, $O_{10}^{+}(q)$, $O_{10}^{-}(q)$ or $O_{12}^{+}(q)$, with $q$ odd. We prove that every finite group having the sa…
