Abstract:
Isospectral are the groups with coinciding sets of element orders. We prove that no finite group isospectral to a finite simple classical group has the exceptional groups of types $E_7$ and $E_8$ among its nonabelian composition factors.
Keywords:
simple classical group, exceptional group of Lie type, element orders, recognition by spectrum.
