Subgroup ($H$) information

Description:$C_{235}$
Order: \(235\)\(\medspace = 5 \cdot 47 \)
Index: \(2\)
Exponent: \(235\)\(\medspace = 5 \cdot 47 \)
Generators: $b^{141}, b^{5}$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is the Fitting subgroup (hence characteristic, normal, nilpotent, solvable, supersolvable, and monomial), the socle, maximal, a semidirect factor, cyclic (hence abelian, elementary ($p = 5,47$), hyperelementary, metacyclic, metabelian, a Z-group, and an A-group), and a Hall subgroup.

Ambient group ($G$) information

Description: $C_5\times D_{47}$
Order: \(470\)\(\medspace = 2 \cdot 5 \cdot 47 \)
Exponent: \(470\)\(\medspace = 2 \cdot 5 \cdot 47 \)
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: $C_2$
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

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_{47}:(C_2\times C_{92})$
$\operatorname{Aut}(H)$ $C_2\times C_{92}$, of order \(184\)\(\medspace = 2^{3} \cdot 23 \)
$\operatorname{res}(\operatorname{Aut}(G))$$C_2\times C_{92}$, of order \(184\)\(\medspace = 2^{3} \cdot 23 \)
$\card{\operatorname{ker}(\operatorname{res})}$\(47\)
