In the general case, the order of a finite nonidentity group $G$ is substantially larger than the squared degree of every irreducible character $\Theta$ of $G$, i.e., $\Theta(1)^2|G|$. In the present paper, we study finite groups with an irreducible character $\Theta$ such that $$ |G|\le 2\Theta(1)^2. $$
Keywords: finite group, irreducible character, Sylow subgroup, Clifford theory, Fitting subgroup.
Mots-clés : Frobenius group, constituent, Galois group
