Subgroup ($H$) information

Description:$C_{12}$
Order: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Index: \(36\)\(\medspace = 2^{2} \cdot 3^{2} \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Generators: $c^{3}, b, c^{6}$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is normal and cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary ($p = 2,3$), hyperelementary, metacyclic, metabelian, a Z-group, and an A-group).

Ambient group ($G$) information

Description: $C_4:C_4\times \He_3$
Order: \(432\)\(\medspace = 2^{4} \cdot 3^{3} \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Nilpotency class:$2$
Derived length:$2$

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

Quotient group ($Q$) structure

Description: $C_3\times C_{12}$
Order: \(36\)\(\medspace = 2^{2} \cdot 3^{2} \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Automorphism Group: $C_2\times \GL(2,3)$, of order \(96\)\(\medspace = 2^{5} \cdot 3 \)
Outer Automorphisms: $C_2\times \GL(2,3)$, of order \(96\)\(\medspace = 2^{5} \cdot 3 \)
Nilpotency class: $1$
Derived length: $1$

The quotient is abelian (hence nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), elementary for $p = 3$ (hence hyperelementary), and metacyclic.

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_6^2:(D_4\times \GL(2,3))$, of order \(13824\)\(\medspace = 2^{9} \cdot 3^{3} \)
$\operatorname{Aut}(H)$ $C_2^2$, of order \(4\)\(\medspace = 2^{2} \)
$\operatorname{res}(S)$$C_2^2$, of order \(4\)\(\medspace = 2^{2} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(1728\)\(\medspace = 2^{6} \cdot 3^{3} \)
$W$$C_2$, of order \(2\)
