Subgroup ($H$) information

Description:$C_2\times D_{12}$
Order: \(48\)\(\medspace = 2^{4} \cdot 3 \)
Index: \(20\)\(\medspace = 2^{2} \cdot 5 \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Generators: $ab, d^{40}, c^{2}, d^{15}, d^{30}$ Copy content Toggle raw display
Derived length: $2$

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

Ambient group ($G$) information

Description: $S_3\times D_4\times C_{20}$
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: $C_2\times C_{10}$
Order: \(20\)\(\medspace = 2^{2} \cdot 5 \)
Exponent: \(10\)\(\medspace = 2 \cdot 5 \)
Automorphism Group: $C_4\times S_3$, of order \(24\)\(\medspace = 2^{3} \cdot 3 \)
Outer Automorphisms: $C_4\times S_3$, of order \(24\)\(\medspace = 2^{3} \cdot 3 \)
Derived length: $1$

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

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_2^7.C_2^5)$
$\operatorname{Aut}(H)$ $C_2\wr C_2^2\times S_3$, of order \(384\)\(\medspace = 2^{7} \cdot 3 \)
$\operatorname{res}(\operatorname{Aut}(G))$$C_2^4:D_6$, of order \(192\)\(\medspace = 2^{6} \cdot 3 \)
$\card{\operatorname{ker}(\operatorname{res})}$\(64\)\(\medspace = 2^{6} \)
$W$$C_2\times D_6$, of order \(24\)\(\medspace = 2^{3} \cdot 3 \)
