Subgroup ($H$) information

Description:$C_4$
Order: \(4\)\(\medspace = 2^{2} \)
Index: \(432\)\(\medspace = 2^{4} \cdot 3^{3} \)
Exponent: \(4\)\(\medspace = 2^{2} \)
Generators: $\langle(2,5,7,9)(3,8,6,4)(10,13)(11,12), (2,7)(3,6)(4,8)(5,9)\rangle$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary, hyperelementary, metacyclic, metabelian, a Z-group, and an A-group) and a $p$-group.

Ambient group ($G$) information

Description: $C_6^2:\GL(2,3)$
Order: \(1728\)\(\medspace = 2^{6} \cdot 3^{3} \)
Exponent: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Derived length:$5$

The ambient group is nonabelian and 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{res}(S)$$C_2$, of order \(2\)
$\card{\operatorname{ker}(\operatorname{res})}$\(32\)\(\medspace = 2^{5} \)
