Subgroup ($H$) information

Description:$C_3\times Q_8$
Order: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Index: \(72\)\(\medspace = 2^{3} \cdot 3^{2} \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Generators: $\langle(9,12,11)(10,14,13), (1,7,2,8)(3,4,5,6), (1,4,2,6)(3,8,5,7), (1,2)(3,5)(4,6)(7,8)\rangle$ Copy content Toggle raw display
Nilpotency class: $2$
Derived length: $2$

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

Ambient group ($G$) information

Description: $(Q_8\times C_3^2):S_4$
Order: \(1728\)\(\medspace = 2^{6} \cdot 3^{3} \)
Exponent: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Derived length:$4$

The ambient group is nonabelian and monomial (hence solvable).

Quotient group ($Q$) structure

Description: $C_3:S_4$
Order: \(72\)\(\medspace = 2^{3} \cdot 3^{2} \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Automorphism Group: $C_6^2:D_6$, of order \(432\)\(\medspace = 2^{4} \cdot 3^{3} \)
Outer Automorphisms: $S_3$, of order \(6\)\(\medspace = 2 \cdot 3 \)
Nilpotency class: $-1$
Derived length: $3$

The quotient is nonabelian, monomial (hence solvable), 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_2\times C_2^4:\He_3.C_2^4$
$\operatorname{Aut}(H)$ $C_2\times S_4$, of order \(48\)\(\medspace = 2^{4} \cdot 3 \)
$\operatorname{res}(S)$$C_2\times S_4$, of order \(48\)\(\medspace = 2^{4} \cdot 3 \)
$\card{\operatorname{ker}(\operatorname{res})}$\(144\)\(\medspace = 2^{4} \cdot 3^{2} \)
$W$$S_4$, of order \(24\)\(\medspace = 2^{3} \cdot 3 \)
