Subgroup ($H$) information

Description:$C_6:C_8$
Order: \(48\)\(\medspace = 2^{4} \cdot 3 \)
Index: \(28\)\(\medspace = 2^{2} \cdot 7 \)
Exponent: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Generators: $abc, c^{8}, b^{14}, c^{6}, c^{12}$ Copy content Toggle raw display
Derived length: $2$

The subgroup is nonabelian, metacyclic (hence solvable, supersolvable, monomial, and metabelian), hyperelementary for $p = 2$, and an A-group.

Ambient group ($G$) information

Description: $C_{24}:D_{28}$
Order: \(1344\)\(\medspace = 2^{6} \cdot 3 \cdot 7 \)
Exponent: \(168\)\(\medspace = 2^{3} \cdot 3 \cdot 7 \)
Derived length:$2$

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

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_2^7\times S_3\times F_7$
$\operatorname{Aut}(H)$ $D_4\times D_6$, of order \(96\)\(\medspace = 2^{5} \cdot 3 \)
$\operatorname{res}(S)$$C_2^2\times D_6$, of order \(48\)\(\medspace = 2^{4} \cdot 3 \)
$\card{\operatorname{ker}(\operatorname{res})}$\(96\)\(\medspace = 2^{5} \cdot 3 \)
$W$$C_2\times D_6$, of order \(24\)\(\medspace = 2^{3} \cdot 3 \)
