Subgroup ($H$) information

Description:$C_2\times C_{12}$
Order: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Index: \(40\)\(\medspace = 2^{3} \cdot 5 \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Generators: $\left(\begin{array}{rr} 8 & 39 \\ 13 & 14 \end{array}\right), \left(\begin{array}{rr} 1 & 22 \\ 22 & 1 \end{array}\right), \left(\begin{array}{rr} 25 & 4 \\ 16 & 29 \end{array}\right), \left(\begin{array}{rr} 43 & 22 \\ 22 & 43 \end{array}\right)$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

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

Ambient group ($G$) information

Description: $C_2^2:D_{12}\times C_{10}$
Order: \(960\)\(\medspace = 2^{6} \cdot 3 \cdot 5 \)
Exponent: \(60\)\(\medspace = 2^{2} \cdot 3 \cdot 5 \)
Derived length:$2$

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

Quotient group ($Q$) structure

Description: $C_2^2\times C_{10}$
Order: \(40\)\(\medspace = 2^{3} \cdot 5 \)
Exponent: \(10\)\(\medspace = 2 \cdot 5 \)
Automorphism Group: $C_4\times \GL(3,2)$, of order \(672\)\(\medspace = 2^{5} \cdot 3 \cdot 7 \)
Outer Automorphisms: $C_4\times \GL(3,2)$, of order \(672\)\(\medspace = 2^{5} \cdot 3 \cdot 7 \)
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

While the subgroup $H$ is not characteristic, the stabilizer $S$ of $H$ in the automorphism group $\operatorname{Aut}(G)$ of the ambient group acts on $H$, yielding a homomorphism $\operatorname{res} : S \to \operatorname{Aut}(H)$. The image of $\operatorname{res}$ on the inner automorphisms $\operatorname{Inn}(G) \cap S$ is the Weyl group $W = N_G(H) / Z_G(H)$.

$\operatorname{Aut}(G)$$C_3:(C_2^6.C_2^5.C_2^4)$
$\operatorname{Aut}(H)$ $C_2\times D_4$, of order \(16\)\(\medspace = 2^{4} \)
$\operatorname{res}(S)$$C_2^3$, of order \(8\)\(\medspace = 2^{3} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(3072\)\(\medspace = 2^{10} \cdot 3 \)
$W$$C_2^2$, of order \(4\)\(\medspace = 2^{2} \)
