Subgroup ($H$) information

Description:$C_6\times C_{12}$
Order: \(72\)\(\medspace = 2^{3} \cdot 3^{2} \)
Index: \(8\)\(\medspace = 2^{3} \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Generators: $b, b^{2}, c^{6}, c^{4}, d$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is normal, abelian (hence nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), and metacyclic.

Ambient group ($G$) information

Description: $C_6.(D_4\times C_{12})$
Order: \(576\)\(\medspace = 2^{6} \cdot 3^{2} \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Derived length:$2$

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

Quotient group ($Q$) structure

Description: $C_2\times C_4$
Order: \(8\)\(\medspace = 2^{3} \)
Exponent: \(4\)\(\medspace = 2^{2} \)
Automorphism Group: $D_4$, of order \(8\)\(\medspace = 2^{3} \)
Outer Automorphisms: $D_4$, of order \(8\)\(\medspace = 2^{3} \)
Nilpotency class: $1$
Derived length: $1$

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

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^{10}\times S_3$
$\operatorname{Aut}(H)$ $D_4\times \GL(2,3)$, of order \(384\)\(\medspace = 2^{7} \cdot 3 \)
$\operatorname{res}(S)$$C_2^4$, of order \(16\)\(\medspace = 2^{4} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(192\)\(\medspace = 2^{6} \cdot 3 \)
$W$$C_2^2$, of order \(4\)\(\medspace = 2^{2} \)
