Subgroup ($H$) information

Description:$C_7$
Order: \(7\)
Index: \(224\)\(\medspace = 2^{5} \cdot 7 \)
Exponent: \(7\)
Generators: $b^{2}c^{24}$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

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

Ambient group ($G$) information

Description: $C_{56}.D_{14}$
Order: \(1568\)\(\medspace = 2^{5} \cdot 7^{2} \)
Exponent: \(56\)\(\medspace = 2^{3} \cdot 7 \)
Derived length:$2$

The ambient group is nonabelian, supersolvable (hence solvable and monomial), and metabelian.

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_7^2.C_6^2.C_2^5$
$\operatorname{Aut}(H)$ $C_6$, of order \(6\)\(\medspace = 2 \cdot 3 \)
