Subgroup ($H$) information

Description:$Q_{64}$
Order: \(64\)\(\medspace = 2^{6} \)
Index: \(23\)
Exponent: \(32\)\(\medspace = 2^{5} \)
Generators: $a, b^{23}$ Copy content Toggle raw display
Nilpotency class: $5$
Derived length: $2$

The subgroup is maximal, nonabelian, a $2$-Sylow subgroup (hence nilpotent, solvable, supersolvable, a Hall subgroup, and monomial), a $p$-group (hence elementary and hyperelementary), and metacyclic (hence metabelian).

Ambient group ($G$) information

Description: $C_{23}:Q_{64}$
Order: \(1472\)\(\medspace = 2^{6} \cdot 23 \)
Exponent: \(736\)\(\medspace = 2^{5} \cdot 23 \)
Derived length:$2$

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

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 $W = N_G(H) / Z_G(H)$.
