Subgroup ($H$) information

Description:$C_2^2\times C_{12}$
Order: \(48\)\(\medspace = 2^{4} \cdot 3 \)
Index: \(8\)\(\medspace = 2^{3} \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Generators: $b^{2}, b^{4}, cd^{6}, d^{6}, d^{4}$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is the commutator subgroup (hence characteristic and normal), abelian (hence nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), and elementary for $p = 2$ (hence hyperelementary).

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: $C_2^3$
Order: \(8\)\(\medspace = 2^{3} \)
Exponent: \(2\)
Automorphism Group: $\PSL(2,7)$, of order \(168\)\(\medspace = 2^{3} \cdot 3 \cdot 7 \)
Outer Automorphisms: $\PSL(2,7)$, of order \(168\)\(\medspace = 2^{3} \cdot 3 \cdot 7 \)
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 rational.

Automorphism information

Since the subgroup $H$ is characteristic, the automorphism group $\operatorname{Aut}(G)$ of the ambient group acts on $H$, yielding a homomorphism $\operatorname{res} : \operatorname{Aut}(G) \to \operatorname{Aut}(H)$. The image of $\operatorname{res}$ on the inner automorphism group $\operatorname{Inn}(G)$ is the Weyl group $W = G / Z_G(H)$.

$\operatorname{Aut}(G)$$C_3:(C_2^8.C_2^5)$
$\operatorname{Aut}(H)$ $C_2^4:S_4$, of order \(384\)\(\medspace = 2^{7} \cdot 3 \)
$\card{W}$\(4\)\(\medspace = 2^{2} \)
