Subgroup ($H$) information

Description:$D_6$
Order: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Index: \(225\)\(\medspace = 3^{2} \cdot 5^{2} \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Generators: $ac^{9}, b^{3}, c^{10}d^{10}$ Copy content Toggle raw display
Derived length: $2$

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

Ambient group ($G$) information

Description: $C_{15}^2:D_6$
Order: \(2700\)\(\medspace = 2^{2} \cdot 3^{3} \cdot 5^{2} \)
Exponent: \(30\)\(\medspace = 2 \cdot 3 \cdot 5 \)
Derived length:$3$

The ambient group is nonabelian and monomial (hence 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 $W = N_G(H) / Z_G(H)$.
