Subgroup ($H$) information

Description:$C_3^2:C_8$
Order: \(72\)\(\medspace = 2^{3} \cdot 3^{2} \)
Index: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Exponent: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Generators: $a^{3}, c^{2}, a^{6}, a^{12}, b$ Copy content Toggle raw display
Derived length: $2$

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

Ambient group ($G$) information

Description: $(C_3\times A_4):C_{24}$
Order: \(864\)\(\medspace = 2^{5} \cdot 3^{3} \)
Exponent: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Derived length:$3$

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

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_2^2\times C_6^2:D_6$, of order \(1728\)\(\medspace = 2^{6} \cdot 3^{3} \)
$\operatorname{Aut}(H)$ $C_6^2:\GL(2,3)$, of order \(1728\)\(\medspace = 2^{6} \cdot 3^{3} \)
$\operatorname{res}(S)$$C_6^2:D_6$, of order \(432\)\(\medspace = 2^{4} \cdot 3^{3} \)
$\card{\operatorname{ker}(\operatorname{res})}$$1$
$W$$C_3^2:C_6$, of order \(54\)\(\medspace = 2 \cdot 3^{3} \)
