Subgroup ($H$) information

Description:$C_{22}$
Order: \(22\)\(\medspace = 2 \cdot 11 \)
Index: \(48\)\(\medspace = 2^{4} \cdot 3 \)
Exponent: \(22\)\(\medspace = 2 \cdot 11 \)
Generators: $c^{132}, c^{24}$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is characteristic (hence normal) and cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary ($p = 2,11$), hyperelementary, metacyclic, metabelian, a Z-group, and an A-group).

Ambient group ($G$) information

Description: $C_{24}:D_{22}$
Order: \(1056\)\(\medspace = 2^{5} \cdot 3 \cdot 11 \)
Exponent: \(264\)\(\medspace = 2^{3} \cdot 3 \cdot 11 \)
Derived length:$2$

The ambient group is nonabelian, supersolvable (hence solvable and monomial), hyperelementary for $p = 2$, and metabelian.

Quotient group ($Q$) structure

Description: $C_2\times D_{12}$
Order: \(48\)\(\medspace = 2^{4} \cdot 3 \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Automorphism Group: $C_2\wr C_2^2\times S_3$, of order \(384\)\(\medspace = 2^{7} \cdot 3 \)
Outer Automorphisms: $C_2^2\wr C_2$, of order \(32\)\(\medspace = 2^{5} \)
Nilpotency class: $-1$
Derived length: $2$

The quotient is nonabelian, supersolvable (hence solvable and monomial), hyperelementary for $p = 2$, and metabelian.

Automorphism information

Since the subgroup $H$ is characteristic, the automorphism group $\operatorname{Aut}(G)$ of the ambient group acts on $H$, yielding a homomorphism $\operatorname{res} : \operatorname{Aut}(G) \to \operatorname{Aut}(H)$. The image of $\operatorname{res}$ on the inner automorphism group $\operatorname{Inn}(G)$ is the Weyl group $W = G / Z_G(H)$.

$\operatorname{Aut}(G)$$C_{66}.C_{10}.C_2^5$
$\operatorname{Aut}(H)$ $C_{10}$, of order \(10\)\(\medspace = 2 \cdot 5 \)
$\operatorname{res}(\operatorname{Aut}(G))$$C_{10}$, of order \(10\)\(\medspace = 2 \cdot 5 \)
$\card{\operatorname{ker}(\operatorname{res})}$\(2112\)\(\medspace = 2^{6} \cdot 3 \cdot 11 \)
$W$$C_2$, of order \(2\)
