Subgroup ($H$) information

Description:$C_3:D_4$
Order: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Index: \(40\)\(\medspace = 2^{3} \cdot 5 \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Generators: $abc^{6}, d^{5}, c^{12}, c^{8}$ Copy content Toggle raw display
Derived length: $2$

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

Ambient group ($G$) information

Description: $C_{60}.C_2^4$
Order: \(960\)\(\medspace = 2^{6} \cdot 3 \cdot 5 \)
Exponent: \(120\)\(\medspace = 2^{3} \cdot 3 \cdot 5 \)
Derived length:$2$

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

Quotient group ($Q$) structure

Description: $C_5:D_4$
Order: \(40\)\(\medspace = 2^{3} \cdot 5 \)
Exponent: \(20\)\(\medspace = 2^{2} \cdot 5 \)
Automorphism Group: $C_2^2\times F_5$, of order \(80\)\(\medspace = 2^{4} \cdot 5 \)
Outer Automorphisms: $C_4$, of order \(4\)\(\medspace = 2^{2} \)
Derived length: $2$

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

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_{15}:(C_2^3.C_2^6.C_2)$
$\operatorname{Aut}(H)$ $C_2\times D_6$, of order \(24\)\(\medspace = 2^{3} \cdot 3 \)
$\operatorname{res}(S)$$C_2\times D_6$, of order \(24\)\(\medspace = 2^{3} \cdot 3 \)
$\card{\operatorname{ker}(\operatorname{res})}$\(320\)\(\medspace = 2^{6} \cdot 5 \)
$W$$C_2\times D_6$, of order \(24\)\(\medspace = 2^{3} \cdot 3 \)
