Subgroup ($H$) information

Description:$C_2\times C_4\times C_{12}$
Order: \(96\)\(\medspace = 2^{5} \cdot 3 \)
Index: \(2\)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Generators: $a, c^{6}, a^{2}, b^{2}, c^{3}, c^{4}$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

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

Ambient group ($G$) information

Description: $C_{12}:C_4^2$
Order: \(192\)\(\medspace = 2^{6} \cdot 3 \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Nilpotency class:$2$
Derived length:$2$

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

Quotient group ($Q$) structure

Description: $C_2$
Order: \(2\)
Exponent: \(2\)
Automorphism Group: $C_1$, of order $1$
Outer Automorphisms: $C_1$, of order $1$
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), a $p$-group, simple, 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_2^9.C_2^3$
$\operatorname{Aut}(H)$ $C_2^7:S_4$, of order \(3072\)\(\medspace = 2^{10} \cdot 3 \)
$\card{W}$\(2\)
