Subgroup ($H$) information

Description:$C_2^4$
Order: \(16\)\(\medspace = 2^{4} \)
Index: \(84\)\(\medspace = 2^{2} \cdot 3 \cdot 7 \)
Exponent: \(2\)
Generators: $a, b, c^{2}, d^{42}$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is abelian (hence nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), a $p$-group (hence elementary and hyperelementary), and rational.

Ambient group ($G$) information

Description: $(C_2\times D_{14}):D_{12}$
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.

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_{42}.(C_2^5\times C_6).C_2^4$
$\operatorname{Aut}(H)$ $A_8$, of order \(20160\)\(\medspace = 2^{6} \cdot 3^{2} \cdot 5 \cdot 7 \)
$\card{W}$\(4\)\(\medspace = 2^{2} \)
