Subgroup ($H$) information

Description:$C_{11}\times D_{35}$
Order: \(770\)\(\medspace = 2 \cdot 5 \cdot 7 \cdot 11 \)
Index: $1$
Exponent: \(770\)\(\medspace = 2 \cdot 5 \cdot 7 \cdot 11 \)
Generators: $a, b^{231}, b^{110}, b^{35}$ 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: $C_{11}\times D_{35}$
Order: \(770\)\(\medspace = 2 \cdot 5 \cdot 7 \cdot 11 \)
Exponent: \(770\)\(\medspace = 2 \cdot 5 \cdot 7 \cdot 11 \)
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_{10}\times F_5\times F_7$
$\operatorname{Aut}(H)$ $C_{10}\times F_5\times F_7$
