Subgroup ($H$) information

Description:$C_3\times D_{43}$
Order: \(258\)\(\medspace = 2 \cdot 3 \cdot 43 \)
Index: \(2\)
Exponent: \(258\)\(\medspace = 2 \cdot 3 \cdot 43 \)
Generators: $a, b^{86}, b^{6}$ Copy content Toggle raw display
Derived length: $2$

The subgroup is normal, maximal, 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: $C_3\times D_{86}$
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: $C_2$
Order: \(2\)
Exponent: \(2\)
Automorphism Group: $C_1$, of order $1$
Outer Automorphisms: $C_1$, of order $1$
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

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 $W = N_G(H) / Z_G(H)$.
