Let $\Theta$ be the stabilizer of point in the primitive subgroup $H$ of the symmetric group $S(E)$. If $\Theta$
contains a normal abelian subgroup $\Gamma$ acting as an irreducible subgroup on the normal abelian subgroup
$T \not= 1$ of $H$, then $H$ is conjugated in $S(E)$ to the subgroup of the complete affinne grope of some field. In particular, $\Theta$ can be a splitting extension of $\Gamma$. The way of enumerating is proposed for the finite groups with this property.
