Subgroup ($H$) information

Description:$C_{35}$
Order: \(35\)\(\medspace = 5 \cdot 7 \)
Index: \(46\)\(\medspace = 2 \cdot 23 \)
Exponent: \(35\)\(\medspace = 5 \cdot 7 \)
Generators: $b^{161}, b^{460}$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is characteristic (hence normal), a semidirect factor, cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary ($p = 5,7$), hyperelementary, metacyclic, metabelian, a Z-group, and an A-group), and a Hall subgroup.

Ambient group ($G$) information

Description: $D_{805}$
Order: \(1610\)\(\medspace = 2 \cdot 5 \cdot 7 \cdot 23 \)
Exponent: \(1610\)\(\medspace = 2 \cdot 5 \cdot 7 \cdot 23 \)
Derived length:$2$

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

Quotient group ($Q$) structure

Description: $D_{23}$
Order: \(46\)\(\medspace = 2 \cdot 23 \)
Exponent: \(46\)\(\medspace = 2 \cdot 23 \)
Automorphism Group: $F_{23}$, of order \(506\)\(\medspace = 2 \cdot 11 \cdot 23 \)
Outer Automorphisms: $C_{11}$, of order \(11\)
Nilpotency class: $-1$
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

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_{805}.C_{66}.C_2^3$
$\operatorname{Aut}(H)$ $C_2\times C_{12}$, of order \(24\)\(\medspace = 2^{3} \cdot 3 \)
$\operatorname{res}(\operatorname{Aut}(G))$$C_2\times C_{12}$, of order \(24\)\(\medspace = 2^{3} \cdot 3 \)
$\card{\operatorname{ker}(\operatorname{res})}$\(17710\)\(\medspace = 2 \cdot 5 \cdot 7 \cdot 11 \cdot 23 \)
$W$$C_2$, of order \(2\)
