Subgroup ($H$) information

Description:$C_{10}$
Order: \(10\)\(\medspace = 2 \cdot 5 \)
Index: \(48\)\(\medspace = 2^{4} \cdot 3 \)
Exponent: \(10\)\(\medspace = 2 \cdot 5 \)
Generators: $d^{30}, d^{12}$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is characteristic (hence normal) and cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary ($p = 2,5$), hyperelementary, metacyclic, metabelian, a Z-group, and an A-group).

Ambient group ($G$) information

Description: $C_{60}:C_2^3$
Order: \(480\)\(\medspace = 2^{5} \cdot 3 \cdot 5 \)
Exponent: \(60\)\(\medspace = 2^{2} \cdot 3 \cdot 5 \)
Derived length:$2$

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

Quotient group ($Q$) structure

Description: $C_2^3\times C_6$
Order: \(48\)\(\medspace = 2^{4} \cdot 3 \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Automorphism Group: $C_2\times A_8$, of order \(40320\)\(\medspace = 2^{7} \cdot 3^{2} \cdot 5 \cdot 7 \)
Outer Automorphisms: $C_2\times A_8$, of order \(40320\)\(\medspace = 2^{7} \cdot 3^{2} \cdot 5 \cdot 7 \)
Nilpotency class: $1$
Derived length: $1$

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

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_2^4.C_2^4.C_5.C_6.C_2^3$
$\operatorname{Aut}(H)$ $C_4$, of order \(4\)\(\medspace = 2^{2} \)
$\operatorname{res}(\operatorname{Aut}(G))$$C_4$, of order \(4\)\(\medspace = 2^{2} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(15360\)\(\medspace = 2^{10} \cdot 3 \cdot 5 \)
$W$$C_2$, of order \(2\)
