Subgroup ($H$) information

Description:$C_{34}$
Order: \(34\)\(\medspace = 2 \cdot 17 \)
Index: \(56\)\(\medspace = 2^{3} \cdot 7 \)
Exponent: \(34\)\(\medspace = 2 \cdot 17 \)
Generators: $ab, c^{28}$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is normal, a direct factor, cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary ($p = 2,17$), hyperelementary, metacyclic, metabelian, a Z-group, and an A-group), and central.

Ambient group ($G$) information

Description: $C_2^2\times C_{476}$
Order: \(1904\)\(\medspace = 2^{4} \cdot 7 \cdot 17 \)
Exponent: \(476\)\(\medspace = 2^{2} \cdot 7 \cdot 17 \)
Nilpotency class:$1$
Derived length:$1$

The ambient group is abelian (hence nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group) and elementary for $p = 2$ (hence hyperelementary).

Quotient group ($Q$) structure

Description: $C_2\times C_{28}$
Order: \(56\)\(\medspace = 2^{3} \cdot 7 \)
Exponent: \(28\)\(\medspace = 2^{2} \cdot 7 \)
Automorphism Group: $C_6\times D_4$, of order \(48\)\(\medspace = 2^{4} \cdot 3 \)
Outer Automorphisms: $C_6\times D_4$, of order \(48\)\(\medspace = 2^{4} \cdot 3 \)
Nilpotency class: $1$
Derived length: $1$

The quotient is abelian (hence nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), elementary for $p = 2$ (hence hyperelementary), and metacyclic.

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_2^3:A_4.C_{48}.C_2^2$
$\operatorname{Aut}(H)$ $C_{16}$, of order \(16\)\(\medspace = 2^{4} \)
$\operatorname{res}(S)$$C_{16}$, of order \(16\)\(\medspace = 2^{4} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(192\)\(\medspace = 2^{6} \cdot 3 \)
$W$$C_1$, of order $1$
