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: $a, d^{6}, c^{2}, c, d^{9}, d^{4}$ Copy content Toggle raw display
Nilpotency class: $2$
Derived length: $2$

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

Ambient group ($G$) information

Description: $(C_4\times C_{12}).D_4$
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: $C_4$
Order: \(4\)\(\medspace = 2^{2} \)
Exponent: \(4\)\(\medspace = 2^{2} \)
Automorphism Group: $C_2$, of order \(2\)
Outer Automorphisms: $C_2$, of order \(2\)
Nilpotency class: $1$
Derived length: $1$

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

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_2^6.C_2^6)$
$\operatorname{Aut}(H)$ $C_2^7:D_4$, of order \(1024\)\(\medspace = 2^{10} \)
$\card{W}$\(16\)\(\medspace = 2^{4} \)
