Subgroup ($H$) information

Description:$C_5\times Q_8$
Order: \(40\)\(\medspace = 2^{3} \cdot 5 \)
Index: \(36\)\(\medspace = 2^{2} \cdot 3^{2} \)
Exponent: \(20\)\(\medspace = 2^{2} \cdot 5 \)
Generators: $b^{3}, c^{24}, c^{60}, c^{90}$ Copy content Toggle raw display
Nilpotency class: $2$
Derived length: $2$

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

Ambient group ($G$) information

Description: $C_{120}.D_6$
Order: \(1440\)\(\medspace = 2^{5} \cdot 3^{2} \cdot 5 \)
Exponent: \(120\)\(\medspace = 2^{3} \cdot 3 \cdot 5 \)
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_4^2\times C_3:S_3).C_2^5$
$\operatorname{Aut}(H)$ $C_4\times S_4$, of order \(96\)\(\medspace = 2^{5} \cdot 3 \)
$\operatorname{res}(S)$$C_4\times D_4$, of order \(32\)\(\medspace = 2^{5} \)
