Subgroup ($H$) information

Description:$C_3\times C_{15}$
Order: \(45\)\(\medspace = 3^{2} \cdot 5 \)
Index: \(48\)\(\medspace = 2^{4} \cdot 3 \)
Exponent: \(15\)\(\medspace = 3 \cdot 5 \)
Generators: $\langle(1,5,4,2,3), (6,14,13), (6,14,13)(7,9,8)\rangle$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is characteristic (hence normal), a semidirect factor, abelian (hence nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), elementary for $p = 3$ (hence hyperelementary), and metacyclic.

Ambient group ($G$) information

Description: $S_3^3:C_{10}$
Order: \(2160\)\(\medspace = 2^{4} \cdot 3^{3} \cdot 5 \)
Exponent: \(60\)\(\medspace = 2^{2} \cdot 3 \cdot 5 \)
Derived length:$3$

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

Quotient group ($Q$) structure

Description: $S_3\times D_4$
Order: \(48\)\(\medspace = 2^{4} \cdot 3 \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Automorphism Group: $D_4\times D_6$, of order \(96\)\(\medspace = 2^{5} \cdot 3 \)
Outer Automorphisms: $C_2^2$, of order \(4\)\(\medspace = 2^{2} \)
Nilpotency class: $-1$
Derived length: $2$

The quotient is nonabelian, supersolvable (hence solvable and monomial), hyperelementary for $p = 2$, metabelian, 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_6\times S_3\wr C_2).C_2^3$
$\operatorname{Aut}(H)$ $C_4\times \GL(2,3)$, of order \(192\)\(\medspace = 2^{6} \cdot 3 \)
$\operatorname{res}(\operatorname{Aut}(G))$$C_4\times \SD_{16}$, of order \(64\)\(\medspace = 2^{6} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(54\)\(\medspace = 2 \cdot 3^{3} \)
$W$$D_4$, of order \(8\)\(\medspace = 2^{3} \)
