Subgroup ($H$) information

Description:$D_5$
Order: \(10\)\(\medspace = 2 \cdot 5 \)
Index: \(92\)\(\medspace = 2^{2} \cdot 23 \)
Exponent: \(10\)\(\medspace = 2 \cdot 5 \)
Generators: $ab^{2}, c^{46}$ Copy content Toggle raw display
Derived length: $2$

The subgroup is normal, a direct factor, nonabelian, a Z-group (hence solvable, supersolvable, monomial, metacyclic, metabelian, and an A-group), and hyperelementary for $p = 2$.

Ambient group ($G$) information

Description: $C_{10}.D_{46}$
Order: \(920\)\(\medspace = 2^{3} \cdot 5 \cdot 23 \)
Exponent: \(460\)\(\medspace = 2^{2} \cdot 5 \cdot 23 \)
Derived length:$2$

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

Quotient group ($Q$) structure

Description: $C_{23}:C_4$
Order: \(92\)\(\medspace = 2^{2} \cdot 23 \)
Exponent: \(92\)\(\medspace = 2^{2} \cdot 23 \)
Automorphism Group: $C_2\times F_{23}$, of order \(1012\)\(\medspace = 2^{2} \cdot 11 \cdot 23 \)
Outer Automorphisms: $C_{22}$, of order \(22\)\(\medspace = 2 \cdot 11 \)
Derived length: $2$

The quotient is nonabelian, a Z-group (hence solvable, supersolvable, monomial, metacyclic, metabelian, and an A-group), 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 $W = N_G(H) / Z_G(H)$.

$\operatorname{Aut}(G)$$C_{115}.C_{44}.C_2^3$, of order \(40480\)\(\medspace = 2^{5} \cdot 5 \cdot 11 \cdot 23 \)
$\operatorname{Aut}(H)$ $F_5$, of order \(20\)\(\medspace = 2^{2} \cdot 5 \)
$\operatorname{res}(S)$$F_5$, of order \(20\)\(\medspace = 2^{2} \cdot 5 \)
