Subgroup ($H$) information

Description:$C_3\times D_{29}$
Order: \(174\)\(\medspace = 2 \cdot 3 \cdot 29 \)
Index: \(7\)
Exponent: \(174\)\(\medspace = 2 \cdot 3 \cdot 29 \)
Generators: $a^{3}, a^{2}, b^{7}$ Copy content Toggle raw display
Derived length: $2$

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

Ambient group ($G$) information

Description: $C_{203}:C_6$
Order: \(1218\)\(\medspace = 2 \cdot 3 \cdot 7 \cdot 29 \)
Exponent: \(1218\)\(\medspace = 2 \cdot 3 \cdot 7 \cdot 29 \)
Derived length:$2$

The ambient group is nonabelian and a Z-group (hence solvable, supersolvable, monomial, metacyclic, metabelian, and an A-group).

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_{29}:(C_7^2:(C_2\times C_{12}))$
$\operatorname{Aut}(H)$ $C_2\times F_{29}$, of order \(1624\)\(\medspace = 2^{3} \cdot 7 \cdot 29 \)
$\operatorname{res}(S)$$F_{29}$, of order \(812\)\(\medspace = 2^{2} \cdot 7 \cdot 29 \)
