Subgroup ($H$) information

Description:$\SOPlus(4,2)^2.C_2$
Order: \(10368\)\(\medspace = 2^{7} \cdot 3^{4} \)
Index: \(4\)\(\medspace = 2^{2} \)
Exponent: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Generators: $\langle(1,4,7)(2,5,8)(3,6,9)(10,14,15)(11,12,16)(13,17,18), (10,11,18)(12,13,14) \!\cdots\! \rangle$ Copy content Toggle raw display
Derived length: $3$

The subgroup is nonabelian and solvable. Whether it is monomial has not been computed.

Ambient group ($G$) information

Description: $\SOPlus(4,2)^2.D_4$
Order: \(41472\)\(\medspace = 2^{9} \cdot 3^{4} \)
Exponent: \(48\)\(\medspace = 2^{4} \cdot 3 \)
Derived length:$4$

The ambient group is nonabelian and monomial (hence solvable).

Automorphism information

While the subgroup $H$ is not characteristic, the stabilizer $S$ of $H$ in the automorphism group $\operatorname{Aut}(G)$ of the ambient group acts on $H$, yielding a homomorphism $\operatorname{res} : S \to \operatorname{Aut}(H)$. The image of $\operatorname{res}$ on the inner automorphisms $\operatorname{Inn}(G) \cap S$ is the Weyl group $W = N_G(H) / Z_G(H)$.

$\operatorname{Aut}(G)$$\SOPlus(4,2)^2.D_4$, of order \(41472\)\(\medspace = 2^{9} \cdot 3^{4} \)
$\operatorname{Aut}(H)$ $C_3^4.C_4^2.C_2^4$, of order \(20736\)\(\medspace = 2^{8} \cdot 3^{4} \)
$\card{W}$\(20736\)\(\medspace = 2^{8} \cdot 3^{4} \)
