Subgroup ($H$) information

Description:$S_3$
Order: \(6\)\(\medspace = 2 \cdot 3 \)
Index: \(150\)\(\medspace = 2 \cdot 3 \cdot 5^{2} \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Generators: $ab, c^{10}$ Copy content Toggle raw display
Derived length: $2$

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

Ambient group ($G$) information

Description: $C_{15}^2:C_2^2$
Order: \(900\)\(\medspace = 2^{2} \cdot 3^{2} \cdot 5^{2} \)
Exponent: \(30\)\(\medspace = 2 \cdot 3 \cdot 5 \)
Derived length:$2$

The ambient group is nonabelian, supersolvable (hence solvable and monomial), metabelian, and an A-group.

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_{10}^2.C_{12}.C_4.C_2^2$
