Nilpotency class: | $1$ |
Derived length: | $1$ |
The subgroup is characteristic (hence normal), cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary, hyperelementary, metacyclic, metabelian, a Z-group, and an A-group), and a $p$-group.
Ambient group ($G$) information
Description: | $D_{32}:C_2$ |
Order: | \(128\)\(\medspace = 2^{7} \) |
Exponent: | \(32\)\(\medspace = 2^{5} \) |
Nilpotency class: | $5$ |
Derived length: | $2$ |
The ambient group is nonabelian, a $p$-group (hence nilpotent, solvable, supersolvable, monomial, elementary, and hyperelementary), and metabelian.
Quotient group ($Q$) structure
Description: | $C_2^2$ |
Order: | \(4\)\(\medspace = 2^{2} \) |
Exponent: | \(2\) |
Automorphism Group: | $S_3$, of order \(6\)\(\medspace = 2 \cdot 3 \) |
Outer Automorphisms: | $S_3$, of order \(6\)\(\medspace = 2 \cdot 3 \) |
Nilpotency class: | $1$ |
Derived length: | $1$ |
The quotient is abelian (hence nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), a $p$-group (hence elementary and hyperelementary), metacyclic, and rational.
Automorphism information
Since the subgroup $H$ is characteristic, the automorphism group $\operatorname{Aut}(G)$ of the ambient group acts on $H$, yielding a homomorphism $\operatorname{res} : \operatorname{Aut}(G) \to \operatorname{Aut}(H)$. The image of $\operatorname{res}$ on the inner automorphism group $\operatorname{Inn}(G)$ is the Weyl group $W = G / Z_G(H)$.
$\operatorname{Aut}(G)$ | $C_2\times D_{32}:C_8$, of order \(1024\)\(\medspace = 2^{10} \) |
$\operatorname{Aut}(H)$ | $C_2\times C_8$, of order \(16\)\(\medspace = 2^{4} \) |
$\operatorname{res}(\operatorname{Aut}(G))$ | $C_2\times C_8$, of order \(16\)\(\medspace = 2^{4} \) |
$\card{\operatorname{ker}(\operatorname{res})}$ | \(64\)\(\medspace = 2^{6} \) |
$W$ | $C_2$, of order \(2\) |
