Subgroup ($H$) information

Description:$C_2\times C_4:C_{12}$
Order: \(96\)\(\medspace = 2^{5} \cdot 3 \)
Index: \(4\)\(\medspace = 2^{2} \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Generators: $abcd^{3}, cd^{6}, b^{4}, b^{2}cd^{6}, d^{6}, d^{4}$ Copy content Toggle raw display
Nilpotency class: $2$
Derived length: $2$

The subgroup is normal, nonabelian, elementary for $p = 2$ (hence nilpotent, solvable, supersolvable, monomial, and hyperelementary), and metabelian.

Ambient group ($G$) information

Description: $(C_2\times C_4^2).D_6$
Order: \(384\)\(\medspace = 2^{7} \cdot 3 \)
Exponent: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Derived length:$2$

The ambient group is nonabelian, supersolvable (hence solvable and monomial), hyperelementary for $p = 2$, and metabelian.

Quotient group ($Q$) structure

Description: $C_2^2$
Order: \(4\)\(\medspace = 2^{2} \)
Exponent: \(2\)
Automorphism Group: $S_3$, of order \(6\)\(\medspace = 2 \cdot 3 \)
Outer Automorphisms: $S_3$, of order \(6\)\(\medspace = 2 \cdot 3 \)
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), metacyclic, and rational.

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_3:(C_2^9.C_2^5)$
$\operatorname{Aut}(H)$ $C_2^7:D_4$, of order \(1024\)\(\medspace = 2^{10} \)
$\operatorname{res}(S)$$D_4:C_2^4$, of order \(128\)\(\medspace = 2^{7} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(192\)\(\medspace = 2^{6} \cdot 3 \)
$W$$C_2\times D_4$, of order \(16\)\(\medspace = 2^{4} \)
