Subgroup ($H$) information

Description:$C_2\times C_{40}$
Order: \(80\)\(\medspace = 2^{4} \cdot 5 \)
Index: \(242\)\(\medspace = 2 \cdot 11^{2} \)
Exponent: \(40\)\(\medspace = 2^{3} \cdot 5 \)
Generators: $b, a^{2}c^{6}d^{8}, b^{2}, d^{11}, d^{22}$ 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: $C_{11}^2:(C_{10}\times \SD_{16})$
Order: \(19360\)\(\medspace = 2^{5} \cdot 5 \cdot 11^{2} \)
Exponent: \(440\)\(\medspace = 2^{3} \cdot 5 \cdot 11 \)
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_{11}^2.C_2^3.C_5.C_2^5$
$\operatorname{Aut}(H)$ $C_4^2:C_2^2$, of order \(64\)\(\medspace = 2^{6} \)
$W$$C_2$, of order \(2\)
