Subgroup ($H$) information

Description:$C_3^2$
Order: \(9\)\(\medspace = 3^{2} \)
Index: \(32\)\(\medspace = 2^{5} \)
Exponent: \(3\)
Generators: $b^{2}c^{4}, c^{4}$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is characteristic (hence normal), a semidirect factor, abelian (hence nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), a $3$-Sylow subgroup (hence a Hall subgroup), a $p$-group (hence elementary and hyperelementary), and metacyclic.

Ambient group ($G$) information

Description: $(C_6\times C_{12}):C_4$
Order: \(288\)\(\medspace = 2^{5} \cdot 3^{2} \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Derived length:$2$

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

Quotient group ($Q$) structure

Description: $C_2.C_4^2$
Order: \(32\)\(\medspace = 2^{5} \)
Exponent: \(4\)\(\medspace = 2^{2} \)
Automorphism Group: $C_2\wr S_3$, of order \(384\)\(\medspace = 2^{7} \cdot 3 \)
Outer Automorphisms: $\GL(2,\mathbb{Z}/4)$, of order \(96\)\(\medspace = 2^{5} \cdot 3 \)
Nilpotency class: $2$
Derived length: $2$

The quotient is nonabelian, a $p$-group (hence nilpotent, solvable, supersolvable, monomial, elementary, and hyperelementary), and metabelian.

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:S_3.C_2^5.C_2^3$
$\operatorname{Aut}(H)$ $\GL(2,3)$, of order \(48\)\(\medspace = 2^{4} \cdot 3 \)
$\operatorname{res}(\operatorname{Aut}(G))$$\SD_{16}$, of order \(16\)\(\medspace = 2^{4} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(288\)\(\medspace = 2^{5} \cdot 3^{2} \)
$W$$C_4$, of order \(4\)\(\medspace = 2^{2} \)
