Subgroup ($H$) information

Description:$C_2^2\times C_6$
Order: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Index: \(36\)\(\medspace = 2^{2} \cdot 3^{2} \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Generators: $\langle(9,11,10), (3,7)(5,8), (2,6)(3,7), (1,4)(2,6)(3,7)(5,8)\rangle$ 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), and elementary for $p = 2$ (hence hyperelementary).

Ambient group ($G$) information

Description: $C_3^2\times Q_8:A_4$
Order: \(864\)\(\medspace = 2^{5} \cdot 3^{3} \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Derived length:$3$

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

Quotient group ($Q$) structure

Description: $C_3\times A_4$
Order: \(36\)\(\medspace = 2^{2} \cdot 3^{2} \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Automorphism Group: $S_3\times S_4$, of order \(144\)\(\medspace = 2^{4} \cdot 3^{2} \)
Outer Automorphisms: $D_6$, of order \(12\)\(\medspace = 2^{2} \cdot 3 \)
Nilpotency class: $-1$
Derived length: $2$

The quotient is nonabelian, monomial (hence solvable), metabelian, and an A-group.

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_3:S_3.C_2^6.S_3^3$
$\operatorname{Aut}(H)$ $C_2\times \GL(3,2)$, of order \(336\)\(\medspace = 2^{4} \cdot 3 \cdot 7 \)
$\operatorname{res}(S)$$C_2\times S_4$, of order \(48\)\(\medspace = 2^{4} \cdot 3 \)
$\card{\operatorname{ker}(\operatorname{res})}$\(432\)\(\medspace = 2^{4} \cdot 3^{3} \)
$W$$A_4$, of order \(12\)\(\medspace = 2^{2} \cdot 3 \)
