Subgroup ($H$) information

Description:$C_3:C_{12}$
Order: \(36\)\(\medspace = 2^{2} \cdot 3^{2} \)
Index: \(8\)\(\medspace = 2^{3} \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Generators: $b^{3}c^{18}, b^{2}, c^{12}, c^{8}$ Copy content Toggle raw display
Derived length: $2$

The subgroup is characteristic (hence normal), nonabelian, metacyclic (hence solvable, supersolvable, monomial, and metabelian), and an A-group.

Ambient group ($G$) information

Description: $C_{24}:D_6$
Order: \(288\)\(\medspace = 2^{5} \cdot 3^{2} \)
Exponent: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Derived length:$2$

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

Quotient group ($Q$) structure

Description: $D_4$
Order: \(8\)\(\medspace = 2^{3} \)
Exponent: \(4\)\(\medspace = 2^{2} \)
Automorphism Group: $D_4$, of order \(8\)\(\medspace = 2^{3} \)
Outer Automorphisms: $C_2$, of order \(2\)
Derived length: $2$

The quotient is nonabelian, a $p$-group (hence nilpotent, solvable, supersolvable, monomial, elementary, and hyperelementary), metacyclic (hence metabelian), 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_{12}:C_2^5$, of order \(384\)\(\medspace = 2^{7} \cdot 3 \)
$\operatorname{Aut}(H)$ $C_2\times D_6$, of order \(24\)\(\medspace = 2^{3} \cdot 3 \)
$\operatorname{res}(\operatorname{Aut}(G))$$C_2\times D_6$, of order \(24\)\(\medspace = 2^{3} \cdot 3 \)
$\card{\operatorname{ker}(\operatorname{res})}$\(16\)\(\medspace = 2^{4} \)
$W$$D_6$, of order \(12\)\(\medspace = 2^{2} \cdot 3 \)
