Subgroup ($H$) information

Description:$C_6$
Order: \(6\)\(\medspace = 2 \cdot 3 \)
Index: \(160\)\(\medspace = 2^{5} \cdot 5 \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Generators: $a^{2}c^{15}, c^{20}$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is normal, a semidirect factor, and cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary ($p = 2,3$), hyperelementary, metacyclic, metabelian, a Z-group, and an A-group).

Ambient group ($G$) information

Description: $C_2\times C_{30}.D_8$
Order: \(960\)\(\medspace = 2^{6} \cdot 3 \cdot 5 \)
Exponent: \(120\)\(\medspace = 2^{3} \cdot 3 \cdot 5 \)
Derived length:$2$

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

Quotient group ($Q$) structure

Description: $C_8:C_{20}$
Order: \(160\)\(\medspace = 2^{5} \cdot 5 \)
Exponent: \(40\)\(\medspace = 2^{3} \cdot 5 \)
Automorphism Group: $C_4\times C_2^4.D_4$, of order \(512\)\(\medspace = 2^{9} \)
Outer Automorphisms: $C_4^2:C_2^2$, of order \(64\)\(\medspace = 2^{6} \)
Nilpotency class: $3$
Derived length: $2$

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

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_3:(C_2^5.C_2^6.C_2^2)$
$\operatorname{Aut}(H)$ $C_2$, of order \(2\)
$\card{W}$\(2\)
