Subgroup ($H$) information

Description:$C_{60}:C_2^3$
Order: \(480\)\(\medspace = 2^{5} \cdot 3 \cdot 5 \)
Index: \(2\)
Exponent: \(60\)\(\medspace = 2^{2} \cdot 3 \cdot 5 \)
Generators: $a, c^{4}, c^{2}, d^{15}, b, d^{6}, d^{20}$ Copy content Toggle raw display
Derived length: $2$

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

Ambient group ($G$) information

Description: $C_{60}.C_2^4$
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 $p = 2$, metabelian, and an A-group.

Quotient group ($Q$) structure

Description: $C_2$
Order: \(2\)
Exponent: \(2\)
Automorphism Group: $C_1$, of order $1$
Outer Automorphisms: $C_1$, of order $1$
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_2^4.C_2^4.C_{15}.C_6.C_2^4$
$\operatorname{Aut}(H)$ $C_2^4.C_2^4.C_5.C_6.C_2^3$
$\card{\operatorname{res}(\operatorname{Aut}(G))}$\(15360\)\(\medspace = 2^{10} \cdot 3 \cdot 5 \)
$\card{\operatorname{ker}(\operatorname{res})}$\(24\)\(\medspace = 2^{3} \cdot 3 \)
$W$$D_{10}$, of order \(20\)\(\medspace = 2^{2} \cdot 5 \)
