Subgroup ($H$) information

Description:$S_3$
Order: \(6\)\(\medspace = 2 \cdot 3 \)
Index: \(167\)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Generators: $a, b^{334}$ Copy content Toggle raw display
Derived length: $2$

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

Ambient group ($G$) information

Description: $S_3\times C_{167}$
Order: \(1002\)\(\medspace = 2 \cdot 3 \cdot 167 \)
Exponent: \(1002\)\(\medspace = 2 \cdot 3 \cdot 167 \)
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: $C_{167}$
Order: \(167\)
Exponent: \(167\)
Automorphism Group: $C_{166}$, of order \(166\)\(\medspace = 2 \cdot 83 \)
Outer Automorphisms: $C_{166}$, of order \(166\)\(\medspace = 2 \cdot 83 \)
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, and simple.

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)$$S_3\times C_{166}$, of order \(996\)\(\medspace = 2^{2} \cdot 3 \cdot 83 \)
$\operatorname{Aut}(H)$ $S_3$, of order \(6\)\(\medspace = 2 \cdot 3 \)
$\operatorname{res}(\operatorname{Aut}(G))$$S_3$, of order \(6\)\(\medspace = 2 \cdot 3 \)
$\card{\operatorname{ker}(\operatorname{res})}$\(166\)\(\medspace = 2 \cdot 83 \)
