Subgroup ($H$) information

Description:$C_2^2$
Order: \(4\)\(\medspace = 2^{2} \)
Index: \(19965\)\(\medspace = 3 \cdot 5 \cdot 11^{3} \)
Exponent: \(2\)
Generators: $\left(\begin{array}{rr} 120 & 0 \\ 0 & 1 \end{array}\right), \left(\begin{array}{rr} 120 & 0 \\ 0 & 120 \end{array}\right)$ 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), a $2$-Sylow subgroup (hence a Hall subgroup), a $p$-group (hence elementary and hyperelementary), metacyclic, and rational.

Ambient group ($G$) information

Description: $C_{10}\times C_{11}\wr S_3$
Order: \(79860\)\(\medspace = 2^{2} \cdot 3 \cdot 5 \cdot 11^{3} \)
Exponent: \(330\)\(\medspace = 2 \cdot 3 \cdot 5 \cdot 11 \)
Derived length:$3$

The ambient group is nonabelian, monomial (hence solvable), 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_{11}^2.C_{15}.C_{20}.C_2^4$
$\operatorname{Aut}(H)$ $S_3$, of order \(6\)\(\medspace = 2 \cdot 3 \)
$W$$C_1$, of order $1$
