Subgroup ($H$) information

Description:$C_2\times C_{30}$
Order: \(60\)\(\medspace = 2^{2} \cdot 3 \cdot 5 \)
Index: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Exponent: \(30\)\(\medspace = 2 \cdot 3 \cdot 5 \)
Generators: $c^{3}, c^{2}, d^{12}, d^{30}$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is normal, abelian (hence nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), elementary for $p = 2$ (hence hyperelementary), and metacyclic.

Ambient group ($G$) information

Description: $C_{10}.D_6^2$
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: $C_2\times D_6$
Order: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Automorphism Group: $S_3\times S_4$, of order \(144\)\(\medspace = 2^{4} \cdot 3^{2} \)
Outer Automorphisms: $S_4$, of order \(24\)\(\medspace = 2^{3} \cdot 3 \)
Nilpotency class: $-1$
Derived length: $2$

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

Automorphism information

While the subgroup $H$ is not characteristic, the stabilizer $S$ of $H$ in the automorphism group $\operatorname{Aut}(G)$ of the ambient group acts on $H$, yielding a homomorphism $\operatorname{res} : S \to \operatorname{Aut}(H)$. The image of $\operatorname{res}$ on the inner automorphisms $\operatorname{Inn}(G) \cap S$ is the Weyl group $W = N_G(H) / Z_G(H)$.

$\operatorname{Aut}(G)$$C_4\times (C_3\times C_6).C_2^6.C_2$
$\operatorname{Aut}(H)$ $C_4\times D_6$, of order \(48\)\(\medspace = 2^{4} \cdot 3 \)
$\operatorname{res}(S)$$C_2^2\times C_4$, of order \(16\)\(\medspace = 2^{4} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(144\)\(\medspace = 2^{4} \cdot 3^{2} \)
$W$$C_2^2$, of order \(4\)\(\medspace = 2^{2} \)
