Subgroup ($H$) information

Description:$C_2$
Order: \(2\)
Index: \(450\)\(\medspace = 2 \cdot 3^{2} \cdot 5^{2} \)
Exponent: \(2\)
Generators: $c^{5}$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is characteristic (hence normal), a direct factor, cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary, hyperelementary, metacyclic, metabelian, a Z-group, and an A-group), central, a $p$-group, simple, and rational.

Ambient group ($G$) information

Description: $C_6\times C_5^2:S_3$
Order: \(900\)\(\medspace = 2^{2} \cdot 3^{2} \cdot 5^{2} \)
Exponent: \(30\)\(\medspace = 2 \cdot 3 \cdot 5 \)
Derived length:$3$

The ambient group is nonabelian, monomial (hence solvable), and an A-group.

Quotient group ($Q$) structure

Description: $C_3\times C_5^2:S_3$
Order: \(450\)\(\medspace = 2 \cdot 3^{2} \cdot 5^{2} \)
Exponent: \(30\)\(\medspace = 2 \cdot 3 \cdot 5 \)
Automorphism Group: $C_5^2:(C_4\times D_6)$, of order \(1200\)\(\medspace = 2^{4} \cdot 3 \cdot 5^{2} \)
Outer Automorphisms: $C_2\times C_4$, of order \(8\)\(\medspace = 2^{3} \)
Nilpotency class: $-1$
Derived length: $3$

The quotient is nonabelian, monomial (hence solvable), 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_2\times C_5^2:(C_2\times C_4\times S_3)$
$\operatorname{Aut}(H)$ $C_1$, of order $1$
