Subgroup ($H$) information

Description:$C_2$
Order: \(2\)
Index: \(816\)\(\medspace = 2^{4} \cdot 3 \cdot 17 \)
Exponent: \(2\)
Generators: $b$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

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

Ambient group ($G$) information

Description: $D_{12}.C_{68}$
Order: \(1632\)\(\medspace = 2^{5} \cdot 3 \cdot 17 \)
Exponent: \(408\)\(\medspace = 2^{3} \cdot 3 \cdot 17 \)
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 $W = N_G(H) / Z_G(H)$.
