Subgroup ($H$) information

Description:$C_2\times C_{192}$
Order: \(384\)\(\medspace = 2^{7} \cdot 3 \)
Index: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Exponent: \(192\)\(\medspace = 2^{6} \cdot 3 \)
Generators: $\left(\begin{array}{rr} 25 & 0 \\ 0 & 25 \end{array}\right), \left(\begin{array}{rr} 46 & 0 \\ 0 & 46 \end{array}\right), \left(\begin{array}{rr} 81 & 0 \\ 0 & 112 \end{array}\right), \left(\begin{array}{rr} 5 & 0 \\ 0 & 5 \end{array}\right), \left(\begin{array}{rr} 192 & 0 \\ 0 & 192 \end{array}\right), \left(\begin{array}{rr} 108 & 0 \\ 0 & 108 \end{array}\right), \left(\begin{array}{rr} 186 & 0 \\ 0 & 186 \end{array}\right), \left(\begin{array}{rr} 84 & 0 \\ 0 & 109 \end{array}\right)$ 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), elementary for $p = 2$ (hence hyperelementary), and metacyclic.

Ambient group ($G$) information

Description: $D_{24}.C_{96}$
Order: \(4608\)\(\medspace = 2^{9} \cdot 3^{2} \)
Exponent: \(192\)\(\medspace = 2^{6} \cdot 3 \)
Derived length:$2$

The ambient group is nonabelian, supersolvable (hence solvable and monomial), and metabelian.

Quotient group ($Q$) structure

Description: $D_6$
Order: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Automorphism Group: $D_6$, of order \(12\)\(\medspace = 2^{2} \cdot 3 \)
Outer Automorphisms: $C_2$, of order \(2\)
Nilpotency class: $-1$
Derived length: $2$

The quotient is nonabelian, metacyclic (hence solvable, supersolvable, monomial, and metabelian), hyperelementary for $p = 2$, an A-group, 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)$$C_3:((C_4\times C_8).C_2^6.C_2)$
$\operatorname{Aut}(H)$ $C_{16}.C_2^4$, of order \(256\)\(\medspace = 2^{8} \)
$\operatorname{res}(\operatorname{Aut}(G))$$C_2^3\times C_{16}$, of order \(128\)\(\medspace = 2^{7} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(96\)\(\medspace = 2^{5} \cdot 3 \)
$W$$C_2$, of order \(2\)
