Subgroup ($H$) information

Description:$C_6$
Order: \(6\)\(\medspace = 2 \cdot 3 \)
Index: \(86\)\(\medspace = 2 \cdot 43 \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Generators: $b^{129}, b^{86}$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is the center (hence characteristic, normal, abelian, central, nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), a direct factor, and cyclic (hence elementary ($p = 2,3$), hyperelementary, metacyclic, and a Z-group).

Ambient group ($G$) information

Description: $C_3\times D_{86}$
Order: \(516\)\(\medspace = 2^{2} \cdot 3 \cdot 43 \)
Exponent: \(258\)\(\medspace = 2 \cdot 3 \cdot 43 \)
Derived length:$2$

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

Quotient group ($Q$) structure

Description: $D_{43}$
Order: \(86\)\(\medspace = 2 \cdot 43 \)
Exponent: \(86\)\(\medspace = 2 \cdot 43 \)
Automorphism Group: $F_{43}$, of order \(1806\)\(\medspace = 2 \cdot 3 \cdot 7 \cdot 43 \)
Outer Automorphisms: $C_{21}$, of order \(21\)\(\medspace = 3 \cdot 7 \)
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_{43}:(C_2^2\times C_{42})$
$\operatorname{Aut}(H)$ $C_2$, of order \(2\)
$\operatorname{res}(\operatorname{Aut}(G))$$C_2$, of order \(2\)
$\card{\operatorname{ker}(\operatorname{res})}$\(3612\)\(\medspace = 2^{2} \cdot 3 \cdot 7 \cdot 43 \)
