Abstract

Let p>3p>3 be a prime. For each maximal subgroup HGL(d,p)H\leqslant\mathrm{GL}(d,p) with Hp3d+1|H| \geqslant p^{3d+1}, we construct a dd-generator finite pp-group GG with the property that Aut(G)\mathrm{Aut}(G) induces HH on the Frattini quotient G/Φ(G)G/\Phi(G) and Gpd42|G| \leqslant p^{\frac{d^4}{2}}. A significant feature of this construction is that G|G| is very small compared to H|H|, shedding new light upon a celebrated result of Bryant and Kov\'acs. The groups GG that we exhibit have exponent pp, and of all such groups GG with the desired action of HH on G/Φ(G)G/\Phi(G), the construction yields groups with smallest nilpotency class, and in most cases, the smallest order.
