Subgroup ($H$) information

Description:$C_{129}:C_{42}$
Order: \(5418\)\(\medspace = 2 \cdot 3^{2} \cdot 7 \cdot 43 \)
Index: \(44\)\(\medspace = 2^{2} \cdot 11 \)
Exponent: \(1806\)\(\medspace = 2 \cdot 3 \cdot 7 \cdot 43 \)
Generators: $\left(\begin{array}{rr} 14 & 10 \\ 29 & 30 \end{array}\right), \left(\begin{array}{rr} 7 & 0 \\ 0 & 7 \end{array}\right), \left(\begin{array}{rr} 0 & 32 \\ 24 & 34 \end{array}\right), \left(\begin{array}{rr} 40 & 24 \\ 2 & 15 \end{array}\right), \left(\begin{array}{rr} 6 & 0 \\ 0 & 6 \end{array}\right)$ Copy content Toggle raw display
Derived length: $2$

The subgroup is maximal, nonabelian, metacyclic (hence solvable, supersolvable, monomial, and metabelian), and an A-group.

Ambient group ($G$) information

Description: $C_3\times \SL(2,43)$
Order: \(238392\)\(\medspace = 2^{3} \cdot 3^{2} \cdot 7 \cdot 11 \cdot 43 \)
Exponent: \(39732\)\(\medspace = 2^{2} \cdot 3 \cdot 7 \cdot 11 \cdot 43 \)
Derived length:$1$

The ambient group is nonabelian and nonsolvable.

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

$\operatorname{Aut}(G)$$C_2\times \PSL(2,43).C_2$
$\operatorname{Aut}(H)$ $C_{43}:(C_{42}\times S_3)$
$W$$C_{43}:C_{21}$, of order \(903\)\(\medspace = 3 \cdot 7 \cdot 43 \)
