Subgroup ($H$) information

Description:$C_2\times C_4\times C_{60}$
Order: \(480\)\(\medspace = 2^{5} \cdot 3 \cdot 5 \)
Index: \(2\)
Exponent: \(60\)\(\medspace = 2^{2} \cdot 3 \cdot 5 \)
Generators: $a, b^{4}, c^{15}, c^{40}, b^{2}, c^{30}, c^{12}$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is the Fitting subgroup (hence characteristic, normal, nilpotent, solvable, supersolvable, and monomial), maximal, abelian (hence metabelian and an A-group), and elementary for $p = 2$ (hence hyperelementary).

Ambient group ($G$) information

Description: $C_2\times C_{12}:C_{40}$
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: $C_2$
Order: \(2\)
Exponent: \(2\)
Automorphism Group: $C_1$, of order $1$
Outer Automorphisms: $C_1$, of order $1$
Nilpotency class: $1$
Derived length: $1$

The quotient is cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary, hyperelementary, metacyclic, metabelian, a Z-group, and an A-group), a $p$-group, simple, 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)$$C_3:(C_2^2\times C_4\times C_2^6.C_2^3)$
$\operatorname{Aut}(H)$ $C_2\times C_4\times C_2^6.S_4$
$\operatorname{res}(\operatorname{Aut}(G))$$C_2^3.C_2^6$, of order \(512\)\(\medspace = 2^{9} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(48\)\(\medspace = 2^{4} \cdot 3 \)
$W$$C_2$, of order \(2\)
