Subgroup ($H$) information

Description:$C_2\times C_6$
Order: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Index: \(112\)\(\medspace = 2^{4} \cdot 7 \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Generators: $d^{3}e^{7}, c, d^{2}$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

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

Ambient group ($G$) information

Description: $(C_2^2\times C_6):D_{28}$
Order: \(1344\)\(\medspace = 2^{6} \cdot 3 \cdot 7 \)
Exponent: \(84\)\(\medspace = 2^{2} \cdot 3 \cdot 7 \)
Derived length:$2$

The ambient group is nonabelian, supersolvable (hence solvable and monomial), hyperelementary for $p = 2$, and metabelian.

Quotient group ($Q$) structure

Description: $C_2\times D_{28}$
Order: \(112\)\(\medspace = 2^{4} \cdot 7 \)
Exponent: \(28\)\(\medspace = 2^{2} \cdot 7 \)
Automorphism Group: $C_2\wr C_2^2\times F_7$, of order \(2688\)\(\medspace = 2^{7} \cdot 3 \cdot 7 \)
Outer Automorphisms: $C_2^4:C_6$, of order \(96\)\(\medspace = 2^{5} \cdot 3 \)
Nilpotency class: $-1$
Derived length: $2$

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

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_2^5\times C_{42}).C_6.C_2^5$
$\operatorname{Aut}(H)$ $D_6$, of order \(12\)\(\medspace = 2^{2} \cdot 3 \)
$\card{W}$\(4\)\(\medspace = 2^{2} \)
