Let G be a finite Frobenius group of degree n. We show, by elementary means, that n is a power of some prime p provided the rank \({\mathrm{rk}}(G)\le 3+\sqrt{n+1}\). Then the Frobenius kernel of G agrees with the (unique) Sylow p-subgroup of G. So our result implies the celebrated theorems of Frobenius and Thompson in a special situation.

低等级的Frobenius组
令G为n个阶的有限Frobenius群。我们用基本方法证明,只要等级\({\ mathrm {rk}}(G)\ le 3+ \ sqrt {n + 1} \),n就是一些素数p的幂。然后,G的Frobenius核与G的(唯一)Sylow p-子群一致。因此,我们的结果暗示了在特殊情况下Frobenius和Thompson的著名定理。
