Subgroup ($H$) information

Description:$C_{60}$
Order: \(60\)\(\medspace = 2^{2} \cdot 3 \cdot 5 \)
Index: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Exponent: \(60\)\(\medspace = 2^{2} \cdot 3 \cdot 5 \)
Generators: $c^{15}, c^{12}, c^{30}, c^{40}$ 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 ($p = 2,3,5$), hyperelementary, metacyclic, metabelian, a Z-group, and an A-group).

Ambient group ($G$) information

Description: $C_{30}.(C_4\times D_6)$
Order: \(1440\)\(\medspace = 2^{5} \cdot 3^{2} \cdot 5 \)
Exponent: \(60\)\(\medspace = 2^{2} \cdot 3 \cdot 5 \)
Derived length:$2$

The ambient group is nonabelian, supersolvable (hence solvable and monomial), and metabelian.

Quotient group ($Q$) structure

Description: $C_4\times S_3$
Order: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Automorphism Group: $C_2\times D_6$, of order \(24\)\(\medspace = 2^{3} \cdot 3 \)
Outer Automorphisms: $C_2^2$, of order \(4\)\(\medspace = 2^{2} \)
Nilpotency class: $-1$
Derived length: $2$

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

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_6\times S_3\times D_5).C_2^5$
$\operatorname{Aut}(H)$ $C_2^2\times C_4$, of order \(16\)\(\medspace = 2^{4} \)
$\operatorname{res}(\operatorname{Aut}(G))$$C_2^2\times C_4$, of order \(16\)\(\medspace = 2^{4} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(720\)\(\medspace = 2^{4} \cdot 3^{2} \cdot 5 \)
$W$$C_2\times C_4$, of order \(8\)\(\medspace = 2^{3} \)
