Subgroup ($H$) information

Description:$C_4^2:C_2^2$
Order: \(64\)\(\medspace = 2^{6} \)
Index: \(27\)\(\medspace = 3^{3} \)
Exponent: \(4\)\(\medspace = 2^{2} \)
Generators: $a, b, c^{3}, e^{3}$ Copy content Toggle raw display
Nilpotency class: $2$
Derived length: $2$

The subgroup is nonabelian, a $2$-Sylow subgroup (hence nilpotent, solvable, supersolvable, a Hall subgroup, and monomial), a $p$-group (hence elementary and hyperelementary), and metabelian.

Ambient group ($G$) information

Description: $C_2^3.S_3^3$
Order: \(1728\)\(\medspace = 2^{6} \cdot 3^{3} \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Derived length:$3$

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)$$C_2\times C_2\times S_3\times S_4\times D_6$
$\operatorname{Aut}(H)$ $C_2^7:D_4$, of order \(1024\)\(\medspace = 2^{10} \)
$\operatorname{res}(S)$$C_2^5$, of order \(32\)\(\medspace = 2^{5} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(8\)\(\medspace = 2^{3} \)
$W$$C_2^3$, of order \(8\)\(\medspace = 2^{3} \)
