Characterization of some finite simple groups by biprimaty subgroups. II

In this article, properties of the biprimary subgroups of even order are used to characterize the following series of finite simple groups: the projective special linear groups $PSL(2,q)$, ($q>3$), the projective special unitary groups $PSU(3,2^{2n})$ ($n>1$), the Suzuki groups $\operatorname{Sz}(q)$, the Janko group $J_1$ of order 175560, and the Ree-type groups.
