Subgroup ($H$) information

Description:$C_{15}$
Order: \(15\)\(\medspace = 3 \cdot 5 \)
Index: \(60\)\(\medspace = 2^{2} \cdot 3 \cdot 5 \)
Exponent: \(15\)\(\medspace = 3 \cdot 5 \)
Generators: $c^{10}, c^{3}d^{3}$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary ($p = 3,5$), hyperelementary, metacyclic, metabelian, a Z-group, and an A-group).

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$
$\operatorname{Aut}(H)$ $C_2\times C_4$, of order \(8\)\(\medspace = 2^{3} \)
$\operatorname{res}(S)$$C_2\times C_4$, of order \(8\)\(\medspace = 2^{3} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(2700\)\(\medspace = 2^{2} \cdot 3^{3} \cdot 5^{2} \)
$W$$C_2$, of order \(2\)
