Subgroup ($H$) information

Description:$C_2\times C_{10}$
Order: \(20\)\(\medspace = 2^{2} \cdot 5 \)
Index: \(270\)\(\medspace = 2 \cdot 3^{3} \cdot 5 \)
Exponent: \(10\)\(\medspace = 2 \cdot 5 \)
Generators: $ae^{5}, d^{3}e^{6}, c^{3}$ 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: $C_{15}^2:(C_2\times D_6)$
Order: \(5400\)\(\medspace = 2^{3} \cdot 3^{3} \cdot 5^{2} \)
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 $W = N_G(H) / Z_G(H)$.

$\operatorname{Aut}(G)$$C_5^2.\He_3.C_4.C_2^3$
$\operatorname{Aut}(H)$ $C_4\times S_3$, of order \(24\)\(\medspace = 2^{3} \cdot 3 \)
$W$$C_2$, of order \(2\)
