Subgroup ($H$) information

Description:$Q_8:D_4$
Order: \(64\)\(\medspace = 2^{6} \)
Index: \(486\)\(\medspace = 2 \cdot 3^{5} \)
Exponent: \(8\)\(\medspace = 2^{3} \)
Generators: $\langle(1,5)(2,4)(3,6)(10,14)(11,15)(12,13), (7,9)(10,15)(11,14)(12,13), (1,4) \!\cdots\! \rangle$ Copy content Toggle raw display
Nilpotency class: $3$
Derived length: $2$

The subgroup is nonabelian, a $p$-group (hence nilpotent, solvable, supersolvable, monomial, elementary, and hyperelementary), and metabelian.

Ambient group ($G$) information

Description: $C_3^4:(D_4\times \GL(2,3))$
Order: \(31104\)\(\medspace = 2^{7} \cdot 3^{5} \)
Exponent: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Derived length:$5$

The ambient group is nonabelian and solvable. Whether it is monomial has not been computed.

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_6^2.C_6.D_4.C_2$, of order \(62208\)\(\medspace = 2^{8} \cdot 3^{5} \)
$\operatorname{Aut}(H)$ $C_2^3:D_4^2$, of order \(512\)\(\medspace = 2^{9} \)
$W$$C_2^2\times D_4$, of order \(32\)\(\medspace = 2^{5} \)
