Subgroup ($H$) information

Description:$C_{119}$
Order: \(119\)\(\medspace = 7 \cdot 17 \)
Index: \(56882\)\(\medspace = 2 \cdot 7 \cdot 17 \cdot 239 \)
Exponent: \(119\)\(\medspace = 7 \cdot 17 \)
Generators: $a^{170}b^{510}, b^{1673}$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary ($p = 7,17$), hyperelementary, metacyclic, metabelian, a Z-group, and an A-group).

Ambient group ($G$) information

Description: $C_{28441}:C_{238}$
Order: \(6768958\)\(\medspace = 2 \cdot 7^{2} \cdot 17^{2} \cdot 239 \)
Exponent: \(56882\)\(\medspace = 2 \cdot 7 \cdot 17 \cdot 239 \)
Derived length:$2$

The ambient group is nonabelian, metacyclic (hence solvable, supersolvable, monomial, and 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_{28441}.C_{357}.C_8.C_2^3$
$\operatorname{Aut}(H)$ $C_2\times C_{48}$, of order \(96\)\(\medspace = 2^{5} \cdot 3 \)
$W$$C_1$, of order $1$
