Subgroup ($H$) information

Description:$C_2$
Order: \(2\)
Index: \(2048\)\(\medspace = 2^{11} \)
Exponent: \(2\)
Generators: $\langle(2,16)(3,14)(5,17)(6,18)(8,21)(10,20)(11,24)(12,23)\rangle$ 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, hyperelementary, metacyclic, metabelian, a Z-group, and an A-group), stem (hence central), a $p$-group, simple, and rational. Whether it is a direct factor or a semidirect factor has not been computed.

Ambient group ($G$) information

Description: $(C_2^3\times D_4^2).D_4$
Order: \(4096\)\(\medspace = 2^{12} \)
Exponent: \(8\)\(\medspace = 2^{3} \)
Nilpotency class:$3$
Derived length:$2$

The ambient group is nonabelian, a $p$-group (hence nilpotent, solvable, supersolvable, monomial, elementary, and hyperelementary), metabelian, and rational.

Quotient group ($Q$) structure

Description: $C_2^8.D_4$
Order: \(2048\)\(\medspace = 2^{11} \)
Exponent: \(4\)\(\medspace = 2^{2} \)
Automorphism Group: Group of order \(12884901888\)\(\medspace = 2^{32} \cdot 3 \)
Outer Automorphisms: Group of order \(100663296\)\(\medspace = 2^{25} \cdot 3 \)
Nilpotency class: $3$
Derived length: $2$

The quotient is nonabelian, a $p$-group (hence nilpotent, solvable, supersolvable, monomial, elementary, and hyperelementary), metabelian, and rational.

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 $W = G / Z_G(H)$.

$\operatorname{Aut}(G)$Group of order \(2147483648\)\(\medspace = 2^{31} \)
$\operatorname{Aut}(H)$ $C_1$, of order $1$
