Subgroup ($H$) information

Description:$\OD_{16}:C_2$
Order: \(32\)\(\medspace = 2^{5} \)
Index: \(42\)\(\medspace = 2 \cdot 3 \cdot 7 \)
Exponent: \(8\)\(\medspace = 2^{3} \)
Generators: $a, c, d^{21}$ Copy content Toggle raw display
Nilpotency class: $2$
Derived length: $2$

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

Ambient group ($G$) information

Description: $C_{84}.C_2^4$
Order: \(1344\)\(\medspace = 2^{6} \cdot 3 \cdot 7 \)
Exponent: \(168\)\(\medspace = 2^{3} \cdot 3 \cdot 7 \)
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_2^2$
$\operatorname{Aut}(H)$ $C_2^2\times S_4$, of order \(96\)\(\medspace = 2^{5} \cdot 3 \)
$\card{W}$\(8\)\(\medspace = 2^{3} \)
