Subgroup ($H$) information

Description:$D_4\times D_{14}$
Order: \(224\)\(\medspace = 2^{5} \cdot 7 \)
Index: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Exponent: \(28\)\(\medspace = 2^{2} \cdot 7 \)
Generators: $a, e^{8}, c^{3}, d, be^{42}, e^{28}$ Copy content Toggle raw display
Derived length: $2$

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

Ambient group ($G$) information

Description: $C_8:C_2^3\times F_7$
Order: \(2688\)\(\medspace = 2^{7} \cdot 3 \cdot 7 \)
Exponent: \(168\)\(\medspace = 2^{3} \cdot 3 \cdot 7 \)
Derived length:$2$

The ambient group is nonabelian, supersolvable (hence solvable and monomial), 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_3^4:(D_4\times D_6)$, of order \(172032\)\(\medspace = 2^{13} \cdot 3 \cdot 7 \)
$\operatorname{Aut}(H)$ $F_7\times C_2^5:D_4$, of order \(10752\)\(\medspace = 2^{9} \cdot 3 \cdot 7 \)
$\card{W}$\(168\)\(\medspace = 2^{3} \cdot 3 \cdot 7 \)
