Subgroup ($H$) information

Description:$C_2\times C_4^2\times C_8$
Order: \(256\)\(\medspace = 2^{8} \)
Index: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Exponent: \(8\)\(\medspace = 2^{3} \)
Generators: $\left(\begin{array}{rr} 21 & 0 \\ 0 & 21 \end{array}\right), \left(\begin{array}{rr} 17 & 16 \\ 16 & 1 \end{array}\right), \left(\begin{array}{rr} 9 & 8 \\ 16 & 25 \end{array}\right), \left(\begin{array}{rr} 17 & 8 \\ 24 & 17 \end{array}\right)$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

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

Ambient group ($G$) information

Description: $C_4^4.C_{24}$
Order: \(6144\)\(\medspace = 2^{11} \cdot 3 \)
Exponent: \(48\)\(\medspace = 2^{4} \cdot 3 \)
Derived length:$2$

The ambient group is nonabelian and metabelian (hence solvable). Whether it is monomial has not been computed.

Quotient group ($Q$) structure

Description: $C_2^2\times C_6$
Order: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Automorphism Group: $C_2\times \GL(3,2)$, of order \(336\)\(\medspace = 2^{4} \cdot 3 \cdot 7 \)
Outer Automorphisms: $C_2\times \GL(3,2)$, of order \(336\)\(\medspace = 2^{4} \cdot 3 \cdot 7 \)
Nilpotency class: $1$
Derived length: $1$

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

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)$$C_4^2.(C_2^4\times C_{12}).C_2^6.C_2^3$
$\operatorname{Aut}(H)$ $C_2^{11}.C_2.C_2^6.S_4$
$W$$C_6$, of order \(6\)\(\medspace = 2 \cdot 3 \)
