Subgroup ($H$) information
Description: | $C_2\times C_{48}$ |
Order: | \(96\)\(\medspace = 2^{5} \cdot 3 \) |
Index: | \(2\) |
Exponent: | \(48\)\(\medspace = 2^{4} \cdot 3 \) |
Generators: |
$a^{2}, b^{24}, b^{12}, b^{3}, b^{16}, b^{6}$
|
Nilpotency class: | $1$ |
Derived length: | $1$ |
The subgroup is normal, maximal, central (hence abelian, nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), elementary for $p = 2$ (hence hyperelementary), and metacyclic.
Ambient group ($G$) information
Description: | $C_4\times C_{48}$ |
Order: | \(192\)\(\medspace = 2^{6} \cdot 3 \) |
Exponent: | \(48\)\(\medspace = 2^{4} \cdot 3 \) |
Nilpotency class: | $1$ |
Derived length: | $1$ |
The ambient group is abelian (hence nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), elementary for $p = 2$ (hence hyperelementary), and metacyclic.
Quotient group ($Q$) structure
Description: | $C_2$ |
Order: | \(2\) |
Exponent: | \(2\) |
Automorphism Group: | $C_1$, of order $1$ |
Outer Automorphisms: | $C_1$, of order $1$ |
Nilpotency class: | $1$ |
Derived length: | $1$ |
The quotient 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.
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 $W = N_G(H) / Z_G(H)$.
$\operatorname{Aut}(G)$ | $C_2^6.D_4$, of order \(512\)\(\medspace = 2^{9} \) |
$\operatorname{Aut}(H)$ | $D_4:C_2^3$, of order \(64\)\(\medspace = 2^{6} \) |
$\operatorname{res}(S)$ | $D_4:C_2^3$, of order \(64\)\(\medspace = 2^{6} \) |
$\card{\operatorname{ker}(\operatorname{res})}$ | \(4\)\(\medspace = 2^{2} \) |
$W$ | $C_1$, of order $1$ |
