Subgroup ($H$) information

Description:$C_7$
Order: \(7\)
Index: \(16464\)\(\medspace = 2^{4} \cdot 3 \cdot 7^{3} \)
Exponent: \(7\)
Generators: $d^{2}e^{4}f^{3}$ 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: $D_7\times C_7^3:S_4$
Order: \(115248\)\(\medspace = 2^{4} \cdot 3 \cdot 7^{4} \)
Exponent: \(84\)\(\medspace = 2^{2} \cdot 3 \cdot 7 \)
Derived length:$4$

The ambient group is nonabelian and solvable. Whether it is monomial has not been computed.

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_7^3.(C_7\times A_4).C_6^2.C_2$
$\operatorname{Aut}(H)$ $C_6$, of order \(6\)\(\medspace = 2 \cdot 3 \)
$W$$C_3$, of order \(3\)
