Subgroup ($H$) information

Description:$D_{30}$
Order: \(60\)\(\medspace = 2^{2} \cdot 3 \cdot 5 \)
Index: \(16\)\(\medspace = 2^{4} \)
Exponent: \(30\)\(\medspace = 2 \cdot 3 \cdot 5 \)
Generators: $b, c^{2}, e^{4}, c^{3}e^{10}$ 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: $\GL(2,3):D_{10}$
Order: \(960\)\(\medspace = 2^{6} \cdot 3 \cdot 5 \)
Exponent: \(120\)\(\medspace = 2^{3} \cdot 3 \cdot 5 \)
Derived length:$4$

The ambient group is nonabelian and 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 D_5\times A_4).C_2^5$
$\operatorname{Aut}(H)$ $D_6\times F_5$, of order \(240\)\(\medspace = 2^{4} \cdot 3 \cdot 5 \)
$\card{W}$\(30\)\(\medspace = 2 \cdot 3 \cdot 5 \)
