Subgroup ($H$) information

Description:$C_2\times C_{12}$
Order: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Index: \(15\)\(\medspace = 3 \cdot 5 \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Generators: $a^{3}, b^{15}, b^{40}, b^{30}$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

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

Ambient group ($G$) information

Description: $C_{60}:C_6$
Order: \(360\)\(\medspace = 2^{3} \cdot 3^{2} \cdot 5 \)
Exponent: \(60\)\(\medspace = 2^{2} \cdot 3 \cdot 5 \)
Derived length:$2$

The ambient group is nonabelian, metacyclic (hence solvable, supersolvable, monomial, and 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_2^2\times \GL(2,3)\times F_5$
$\operatorname{Aut}(H)$ $C_2\times D_4$, of order \(16\)\(\medspace = 2^{4} \)
$\operatorname{res}(S)$$C_2^3$, of order \(8\)\(\medspace = 2^{3} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(24\)\(\medspace = 2^{3} \cdot 3 \)
$W$$C_1$, of order $1$
