Subgroup ($H$) information

Description:$C_{12}$
Order: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Index: \(88\)\(\medspace = 2^{3} \cdot 11 \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Generators: $a^{2}b^{66}, b^{176}, b^{132}$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is characteristic (hence normal), cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary ($p = 2,3$), hyperelementary, metacyclic, metabelian, a Z-group, and an A-group), and central.

Ambient group ($G$) information

Description: $C_{264}:C_4$
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, metacyclic (hence solvable, supersolvable, monomial, and metabelian), and hyperelementary for $p = 2$.

Quotient group ($Q$) structure

Description: $C_4\times D_{11}$
Order: \(88\)\(\medspace = 2^{3} \cdot 11 \)
Exponent: \(44\)\(\medspace = 2^{2} \cdot 11 \)
Automorphism Group: $C_2^2\times F_{11}$, of order \(440\)\(\medspace = 2^{3} \cdot 5 \cdot 11 \)
Outer Automorphisms: $C_2\times C_{10}$, of order \(20\)\(\medspace = 2^{2} \cdot 5 \)
Nilpotency class: $-1$
Derived length: $2$

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

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_2^3\times C_{11}:C_5).C_2^5$
$\operatorname{Aut}(H)$ $C_2^2$, of order \(4\)\(\medspace = 2^{2} \)
$\operatorname{res}(\operatorname{Aut}(G))$$C_2^2$, of order \(4\)\(\medspace = 2^{2} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(3520\)\(\medspace = 2^{6} \cdot 5 \cdot 11 \)
$W$$C_1$, of order $1$
