Subgroup ($H$) information

Description:$C_2\times C_6$
Order: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Index: \(32\)\(\medspace = 2^{5} \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Generators: $a, d^{3}, d^{2}$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is normal, a semidirect factor, abelian (hence nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), elementary for $p = 2$ (hence hyperelementary), and metacyclic.

Ambient group ($G$) information

Description: $D_{24}:C_2^3$
Order: \(384\)\(\medspace = 2^{7} \cdot 3 \)
Exponent: \(48\)\(\medspace = 2^{4} \cdot 3 \)
Derived length:$2$

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

Quotient group ($Q$) structure

Description: $D_{16}$
Order: \(32\)\(\medspace = 2^{5} \)
Exponent: \(16\)\(\medspace = 2^{4} \)
Automorphism Group: $D_{16}:C_4$, of order \(128\)\(\medspace = 2^{7} \)
Outer Automorphisms: $C_2\times C_4$, of order \(8\)\(\medspace = 2^{3} \)
Nilpotency class: $4$
Derived length: $2$

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

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_2^6.(C_6\times S_4).C_2^4$, of order \(147456\)\(\medspace = 2^{14} \cdot 3^{2} \)
$\operatorname{Aut}(H)$ $D_6$, of order \(12\)\(\medspace = 2^{2} \cdot 3 \)
$\card{W}$\(2\)
