Subgroup ($H$) information

Description:$D_{50}$
Order: \(100\)\(\medspace = 2^{2} \cdot 5^{2} \)
Index: \(166\)\(\medspace = 2 \cdot 83 \)
Exponent: \(50\)\(\medspace = 2 \cdot 5^{2} \)
Generators: $ab^{581}, b^{3984}, b^{3320}, b^{4150}$ Copy content Toggle raw display
Derived length: $2$

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

Ambient group ($G$) information

Description: $C_{83}\times D_{100}$
Order: \(16600\)\(\medspace = 2^{3} \cdot 5^{2} \cdot 83 \)
Exponent: \(8300\)\(\medspace = 2^{2} \cdot 5^{2} \cdot 83 \)
Derived length:$2$

The ambient group is nonabelian, metacyclic (hence solvable, supersolvable, monomial, and metabelian), and hyperelementary for $p = 2$.

Quotient group ($Q$) structure

Description: $C_{166}$
Order: \(166\)\(\medspace = 2 \cdot 83 \)
Exponent: \(166\)\(\medspace = 2 \cdot 83 \)
Automorphism Group: $C_{82}$, of order \(82\)\(\medspace = 2 \cdot 41 \)
Outer Automorphisms: $C_{82}$, of order \(82\)\(\medspace = 2 \cdot 41 \)
Derived length: $1$

The quotient is cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary ($p = 2,83$), hyperelementary, metacyclic, metabelian, a Z-group, 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_{50}.C_{410}.C_2^4$, of order \(328000\)\(\medspace = 2^{6} \cdot 5^{3} \cdot 41 \)
$\operatorname{Aut}(H)$ $C_{50}:C_{20}$, of order \(1000\)\(\medspace = 2^{3} \cdot 5^{3} \)
$W$$D_{50}$, of order \(100\)\(\medspace = 2^{2} \cdot 5^{2} \)
