Subgroup ($H$) information

Description:$C_{201}:C_{400}$
Order: \(80400\)\(\medspace = 2^{4} \cdot 3 \cdot 5^{2} \cdot 67 \)
Index: $1$
Exponent: \(80400\)\(\medspace = 2^{4} \cdot 3 \cdot 5^{2} \cdot 67 \)
Generators: $a^{100}, b^{3}, b^{67}, a^{200}, a^{80}, a^{25}, a^{16}, a^{50}$ Copy content Toggle raw display
Derived length: $2$

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

Ambient group ($G$) information

Description: $C_{201}:C_{400}$
Order: \(80400\)\(\medspace = 2^{4} \cdot 3 \cdot 5^{2} \cdot 67 \)
Exponent: \(80400\)\(\medspace = 2^{4} \cdot 3 \cdot 5^{2} \cdot 67 \)
Derived length:$2$

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

Quotient group ($Q$) structure

Description: $C_1$
Order: $1$
Exponent: $1$
Automorphism Group: $C_1$, of order $1$
Outer Automorphisms: $C_1$, of order $1$
Derived length: $0$

The quotient is cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary (for every $p$), hyperelementary, metacyclic, metabelian, a Z-group, and an A-group), a $p$-group (for every $p$), perfect, and rational.

Automorphism information

Since the subgroup $H$ is characteristic, the automorphism group $\operatorname{Aut}(G)$ of the ambient group acts on $H$, yielding a homomorphism $\operatorname{res} : \operatorname{Aut}(G) \to \operatorname{Aut}(H)$. The image of $\operatorname{res}$ on the inner automorphism group $\operatorname{Inn}(G)$ is the Weyl group $W = G / Z_G(H)$.

$\operatorname{Aut}(G)$$C_{201}.C_{330}.C_2.C_2^5$, of order \(4245120\)\(\medspace = 2^{7} \cdot 3^{2} \cdot 5 \cdot 11 \cdot 67 \)
$\operatorname{Aut}(H)$ $C_{201}.C_{330}.C_2.C_2^5$, of order \(4245120\)\(\medspace = 2^{7} \cdot 3^{2} \cdot 5 \cdot 11 \cdot 67 \)
$W$$D_{201}$, of order \(402\)\(\medspace = 2 \cdot 3 \cdot 67 \)
