Subgroup ($H$) information

Description:$C_2$
Order: \(2\)
Index: \(216\)\(\medspace = 2^{3} \cdot 3^{3} \)
Exponent: \(2\)
Generators: $a^{6}$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

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

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: $D_4\times \He_3$
Order: \(216\)\(\medspace = 2^{3} \cdot 3^{3} \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Automorphism Group: $C_2^4.\SL(3,3)$, of order \(3456\)\(\medspace = 2^{7} \cdot 3^{3} \)
Outer Automorphisms: $C_2\times \GL(2,3)$, of order \(96\)\(\medspace = 2^{5} \cdot 3 \)
Nilpotency class: $2$
Derived length: $2$

The quotient is nonabelian, nilpotent (hence solvable, supersolvable, and monomial), 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_6^2:(D_4\times \GL(2,3))$, of order \(13824\)\(\medspace = 2^{9} \cdot 3^{3} \)
$\operatorname{Aut}(H)$ $C_1$, of order $1$
$\operatorname{res}(\operatorname{Aut}(G))$$C_1$, of order $1$
$\card{\operatorname{ker}(\operatorname{res})}$\(13824\)\(\medspace = 2^{9} \cdot 3^{3} \)
$W$$C_1$, of order $1$
