Subgroup ($H$) information

Description:$C_4:C_{60}$
Order: \(240\)\(\medspace = 2^{4} \cdot 3 \cdot 5 \)
Index: \(4\)\(\medspace = 2^{2} \)
Exponent: \(60\)\(\medspace = 2^{2} \cdot 3 \cdot 5 \)
Generators: $bc, d^{30}, d^{40}, d^{12}, d^{15}, c^{2}$ Copy content Toggle raw display
Nilpotency class: $2$
Derived length: $2$

The subgroup is characteristic (hence normal), a semidirect factor, nonabelian, elementary for $p = 2$ (hence nilpotent, solvable, supersolvable, monomial, and hyperelementary), and metacyclic (hence metabelian).

Ambient group ($G$) information

Description: $S_3\times D_4\times C_{20}$
Order: \(960\)\(\medspace = 2^{6} \cdot 3 \cdot 5 \)
Exponent: \(60\)\(\medspace = 2^{2} \cdot 3 \cdot 5 \)
Derived length:$2$

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

Quotient group ($Q$) structure

Description: $C_2^2$
Order: \(4\)\(\medspace = 2^{2} \)
Exponent: \(2\)
Automorphism Group: $S_3$, of order \(6\)\(\medspace = 2 \cdot 3 \)
Outer Automorphisms: $S_3$, of order \(6\)\(\medspace = 2 \cdot 3 \)
Nilpotency class: $1$
Derived length: $1$

The quotient is abelian (hence nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), a $p$-group (hence elementary and hyperelementary), metacyclic, 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_2^7.C_2^5)$
$\operatorname{Aut}(H)$ $C_2^3.C_2^5$, of order \(256\)\(\medspace = 2^{8} \)
$\operatorname{res}(\operatorname{Aut}(G))$$C_2^3.C_2^5$, of order \(256\)\(\medspace = 2^{8} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(48\)\(\medspace = 2^{4} \cdot 3 \)
$W$$C_2^3$, of order \(8\)\(\medspace = 2^{3} \)
