The Frobenius group G belongs to an important class of groups that more than 100 years ago was defined by F. G. who proved is a semi-direct product normal subgroup K called kernel another non-trivial H the complement. In this case we show few classical finite can be

Abstract Let G be a finite Frobenius group of degree n . We show, by elementary means, that is power some prime p provided the rank $${\mathrm{rk}}(G)\le 3+\sqrt{n+1}$$ rk ( G ) ≤ 3 + <...
